Kodi adipic acid dihydrazide ndi chiyani?

Adipric acid dihhydrazide (ADH): Kuwunika Kwambiri

Adipic acid dihydrazide. Ndiwosinthasintha kwapakatikati ndi mapulogalamu osiyanasiyana chifukwa cha mawonekedwe ake apadera ndi kapangidwe kake. Munkhaniyi, tiona zomwe adipric acid dihhydrazide ndichakuti, njira zake zamankhwala, kaphatikizidwe, njira zamagetsi, zamafakitale, ndi gawo lawo m'magawo osiyanasiyana.

1.

Adipric acid dihhydrazide (ADH) ndi chotupa cha adipic acid, yomwe ndi yolimba ya dicarboxyylic acid ndi njira ya C₆h₁₀o₄. Njira ya diipic ya adipic ili ndi magulu awiri a hydrazide (-Nh-nh₂) yolumikizidwa ndi msana wa adipic ad. Magulu awa hydrazide ogwira ntchito ali ndi nkhawa ya kujambulidwa ndikupanga adh ndiye chomangira chamtengo wapatali popanga mankhwala osiyanasiyana, zida, ndi mankhwala.

Njira ya mankhwala ya adh ndi C₆h₁₄n₄o₂, ndipo kulemera kwake kwa maanthu pafupifupi 174.21 g / Mol. Imawoneka ngati ufa woyera wa kristalo kapena wolimba womwe umasungunuka m'madzi ndi mowa koma osakhazikika mu organic sol.

2. Kapangidwe ka mankhwala a adipic acid dihydrazide

Kapangidwe ka mankhwala a adipric ad dihydrazide kumakhala ndi magulu awiri a hydrazide ogwiritsira ntchito (-Nh-nh₂) ophatikizidwa ndi fupa la hexane. Kapangidwe kameneka kamapatsa Adh kuzengereza kumapangitsa kuti ikhale njira yabwino yothandizira mafakitale osiyanasiyana. Mapangidwe oyambira adh amatha kuyimitsidwa motere:

Hooc-ch-₂-kooh + 2 nh₂-→ hooc-ch-ch - ch

Izi ndizofunikira chifukwa magulu a Hydrazide amatha kupanga zomangira zokhazikika ndi mankhwala ena, kupanga adh kukhala wapakati papanga mankhwala ena.

3. Katundu wa adipic acid dihydrazide

Adipric acid dihhydrazide ali ndi zinthu zingapo zazikulu zamankhwala ndi thupi zomwe zimapangitsa kuti zikhale zothandiza kugwiritsa ntchito mitundu:

• Kulemera kwa maselo: 174.21 g / mol
• Kaonekedwe: Ufa woyera ufa kapena wolimba
• Kusalola: Sungunuka m'madzi ndi mowa; Zopanda zolimbitsa thupi zambiri
• Malo osungunuka: Pafupifupi 179 ° C
• Kutengeka kwa mankhwala: Chifukwa cha kukhalapo kwa magulu a hydrazide, Adh amagwira kwambiri, makamaka amasinthana ndi exophilic poloweza.

Kusungunuka kwa Adh m'madzi kumapangitsa kuti ikhale yofunika kwambiri yopanga mafakitale m'mafakitale komanso mankhwala. Kukhazikitsidwa kwake kumapangitsa kuti zikhale ngati wothandizira wolumikizirana kapena wapakati pa synthesis a mamolekyulu ovuta.

4. Kaphatikizidwe wa adipic acid dihydrazide

Kaphatikizidwe wa adipic acid dihydrazide nthawi zambiri kumaphatikizapo zomwe acipric acid ndi hydrazine (NH₂-NH₂). Mamolekyu awiri a hydrazine adachita ndi magulu a carboxyl a adipic acid, zomwe zimapangitsa kupangidwa kwa diihydrazide.

Makina

Synthesis ikhoza kusweka motere:

1. Kuyambitsa kwa gulu la carboxyl: Magulu a Carboxyl (-cooh) a adipic acid amayambitsidwa ndi hydrazine, yomwe imagwira ndi carbonyl kaboni kaboni karrazone.
2. Hydrazinolysis: Mamolekyu a Hydrazine omwe amalowa m'malo mwa ma bacchutchic omwe amakumana ndi gulu la carbonyl, zomwe zimayambitsa mapangidwe a ma hydrazide ogwira ntchito m'magulu a Hydrazide acid a adiptic acid.
3. Kuyeretsa: Zotsatira zake zimayeretsedwa kudzera pakubweza kapena njira zina kuti mupeze adipic ad diisirazide.

5. Ntchito za adipic acid dihydrazide

Adipic acid dihhydrazide imagwiritsidwa ntchito pamakampani angapo chifukwa cha kukhazikika kwake komanso kusiyanasiyana. Pansipa pali magawo oyamba kumene Adh amagwiritsidwa ntchito:

a. Polymer ndi respen kupanga

Chimodzi mwazinthu zofunikira kwambiri za Adh chili mu kupanga ma polyurethasthes, amalichera, ndi zida zina za polymeric. Magulu a hydrazide ogwira ntchito mu ADh amathandizira kukhala ngati wothandizira wogwirizira mtanda, kukonza zinthu zamakina, kukhazikika kwa matenthedwe, ndi kulimba kwa zinthu komaliza. Adh amagwiritsidwa ntchito kawirikawiri:

• Zovala za Polyirethane: Adh amathandizira kupanga zokutira zolimba kwambiri pamalo osiyanasiyana, kuphatikizapo magetsi, zomanga, ndi ntchito zamagetsi.
• Makompyuta a Polymer: Adh ndi nyumba yomanga yayikulu mu kaphatikizidwe ka polimatides, pounirethas, ndi ma polima ena apamwamba.

b. Makampani opanga mankhwala

Mu gawo la mankhwala, ADH ndi yovuta kwambiri mu kaphatikizidwe ka mankhwala a hydrazone okhazikika ndi mankhwala ena a bioactive. Hydrazones ndi gulu lazinthu zomwe zikuwonetsa zochitika zosiyanasiyana za chilengedwe, kuphatikizapo odana ndi kutupa, anti-khansa, ndi antimicsicrobi, ndi antimicrobi. Adh amagwiritsidwa ntchito:

• Kupanga Mankhwala: Adh imagwiritsidwa ntchito popanga ma hydrazone kuti akutukuka kwa mankhwala atsopano omwe amamwa mankhwala enaake.
• Ma Chemistry amoyo: Adh imagwiritsidwanso ntchito popanga mankhwala opangira mankhwala kuti apange mankhwala okhala ndi bioavailability, kukhazikika, ndi kusankhidwa.

c. Mankhwala Olima

Adh amatenga nawo gawo mu kaphatikizidwe wa abulumicals, monga herbicides, fungicides, fungicides, ndi tizilombo. Izi zimapindula ndi magulu a hydrazide mu adh, omwe amapereka mankhwala ofunikira pakupanga aharchemicals. Adh amagwiritsidwa ntchito posankha:

• Herbicides: Mafuta omwe amalepheretsa kukula kwa mbewu zosafunikira.
• Fungicides: Mankhwala omwe amalepheretsa kukula kwa bowa ndikuumba pa mbewu.
• Tizilombo: Mafuta omwe amapha kapena kuchotsa tizilombo kuchokera ku mbewu.

d. Makampani opanga malemba

M'makampani opanga malembawo, ADh amagwiritsidwa ntchito popanga ulusi wambiri ndi nsalu. Malo olumikizirana olumikizira adh amapangitsa kuti ikhale yothandiza kuti ikhale yothandiza kulimbikitsa mphamvu zamakina, kukhazikika, komanso kukana kuwonongeka kwa zinthu zojambula. Ambiri amagwiritsidwa ntchito popanga:

• Ulusi wolimba: Adh akuwongolera kulimba mtima komanso kulimba kwa ulusi womwe umagwiritsidwa ntchito m'matumba.
• Nsalu zosagwira madzi: Nsale zoyesedwa ndi ADH zimawonetsa kukana madzi osintha, ndikuwapangitsa kukhala oyenera pakugwiritsa ntchito panja.

e. Zovala ndi zojambula

Adipic acid dihhydrazide imagwiritsidwanso ntchito kwambiri pakulankhula ndi mafakitale. ADH imagwira ntchito ngati nthumwi yolumikizirana yomwe imathandizira magwiridwe antchito ndi zokutira, kuwapatsa katundu wapamwamba monga:

• Kukhazikika kwamphamvu
• Kuchuluka kwa mankhwala
• Kupititsa patsogolo kulimba

Zinthu izi zimapangitsa kuti adh-omwe amathandizidwa ndi ADH ndi abwino kugwiritsa ntchito mu mafakitale, mafakitale, ntchito zomangamanga.

f. Kufufuza ndi Kukula

Kuphatikiza pa ntchito zake, adh amagwiritsidwanso ntchito pofufuza ndi chitukuko. Kuchita mogwirizana ndi mankhwala apakatikati kumapangitsa kukhala kofunika mu mawonekedwe opangidwa mwamphamvu zachilengedwe, makamaka pakukula kwa zinthu zatsopano ndi mankhwala. Adh amagwiritsidwa ntchito:

• Kapangidwe ka zatsopano: Ofufuzawo amagwiritsa ntchito ADh kuti apange mankhwala atsopano a hydrazone okhala ndi zinthu zapadera.
• Sayansi Yathupi: Adh amagwiritsidwa ntchito polenga zida zatsopano zomwe zimakhala ndi magwiridwe antchito, monga kuchuluka kapena kukana kuwonongeka.

6. Chitetezo ndikugwira ntchito a adipic acid dihydrazide

Pomwe Adipic acid dihhydrazide nthawi zambiri amadziwika kuti amagwiritsidwa ntchito moyenera, ndikofunikira kutsatira njira zotetezera pogwira ntchito ndi mankhwalawa. Njira zotsatirazi ziyenera kuwonedwa:

• Zida Zaumwini (PPE): Valani PPE yolondola, kuphatikiza magolovesi, magalasi, ndi zovala za labu, pogwira adh.
• Kutsegulira mphepo: Onetsetsani kuti malo antchito ndi otetezedwa kuti apewe kupuma fumbi kapena nthunzi.
• Kusunga: Sungani Adh pamalo ozizira, owuma, kutali ndi mafupa otentha, ndikuwonetsetsa kuti imasindikizidwa mwamphamvu kuti mupewe kuyamwa chinyezi.
• Kutaya: Kutaya adh malinga ndi malamulo am'deralo ndi malangizo azachilengedwe, monga momwe popanga angawononge zachilengedwe ngati sikataye bwino.

Adipric acid dihydrazide (ADh) ndi yolimba komanso yofunika kwambiri ndi ntchito zambiri zamakampani osiyanasiyana. Kutha kwake kukhala ngati wothandizirana ndi wolumikizirana ndi mankhwalawa kumapangitsa kuti chikhale chinthu chovuta pakupanga ma poizoni, amabwera, mankhwala azaulimi, ndi maulimi. Kaya amagwiritsidwa ntchito popanga zida zapamwamba kwambiri, kukula kwa mankhwala atsopano, kapena kapangidwe kake ka ahachemicals, Adh amatenga mbali yofunika kwambiri yokuthandizani m'magawo angapo.

Monga mankhwala pawiri, Adh amapereka mapindu onse a mafakitale komanso malonda, ndipo kugwiritsidwa ntchito kwake kumayenera kukula monga ntchito zatsopano zapezeka. Kumvetsetsa malo ake, kapangidwe kake, ndipo ntchito ndizofunikira kwa makampani ndi ofufuza omwe akufuna kuti agwirizane ndi ma dipic ad dihsihdrazide pazogulitsa ndi njira zawo.
