Adipic dihydrazide

Adipic dihydrazide(ADH) iyindlela yamakhemikhali ethathwe kuyoadipic acidfuthi linamaqembu amabili e-hydrazide (-nh-nh₂) anamathiselwe esakhiweni se-adipic acid. Isetshenziswa kakhulu njenge-Intermediate ekuthambekeni kwamakhemikhali futhi idlala indima enkulu ezinhlelweni ezahlukahlukene zezimboni kanye nocwaningo. Ngezansi, ngizohlinzeka ngesibukezo se-Compound, izakhiwo zayo, izinhlelo zokusebenza, kanye nokuhlanganiswa.

1. Yini i-adipic dihydrazide (ADH)?

I-Adipic Dihydrazide (ADH)kususelwa kweadipic acid, i-dicarboxylic esetshenziswa kakhulu ye-dicarboxylic, enamaqembu amabili asebenzayo we-hydrazide (-nh-nh₂) anamathele kuwo. I-Compound ivame ukuvezwa yifomulaC₆h₁₄n₄o₂futhi inesisindo samangqamuzana esingaba ngu-174.21 g / mol.

I-adipic dihydrazide yii-crystalline emhlophe eqinile, okuncibilikayo emanzini notshwala. Isakhiwo saso siqukethe okuphakathiadipic acidI-Backbone (C₆H₁₀O₄) nambiliAmaqembu e-Hydrazide(-Nh-nh₂) enamathiselwe kumaqembu e-carboxyl acid adipic. Lesi sakhiwo sinikeza i-Compound Ripnity yayo ehlukile futhi yenza ilungele ukusetshenziswa ezinhlelweni eziningana zezimboni.

2. Izici zamakhemikhali ze-adipic dihydrazide

• Ifomula yamangqamuzana: C₆h₁₄n₄o₂
• Isisindo molecular: 174.21 g / mol
• Ukubonakala: I-White Crystalline powder noma iqinile
• Ubuhlakaniselo: Ukuncibilika emanzini, utshwala; insoluble ku-organic solvents
• Iphuzu elincibilikayo: Approx. 179 ° C
• Ukuphendula kwamakhemikhali: Amaqembu amabili e-hydrazide (-nh-nh₂) anikeze i-ADH RANDIALLICATION, okwenza kube lusizo ekuvuselelekeni okuxhumanisayo, njengommeleli we-polymerization, kanye nokwakha ezinye izinto ezisuselwa ezisekelweni ze-hydrazone.

3. Synthesis we-adipic dihydrazide

Ukuhlanganiswa kweAdipic dihydrazidekubandakanya ukusabela okuqondile phakathiadipic acidna-hydrazine hydrate. Ukusabela kuqhubeka ngokulandelayo:

1. Ukusabela nge-hydrazine: I-Hydrazine (NH₂-NH₂) iphendula nge-adipic acid emazingeni okushisa aphakeme, afaka esikhundleni samaqembu e-carboxyl (-Cooh) e-adipic acid nge-hydrazide (-Conh-NH₂), kwakhekaAdipic dihydrazide.

   
   $Adipic\; acid\; (hooc-CH2-CH2-COOH-COOH-COOH)\; +\; 2hyDrazine\; (NH2-NH2)\; \to \; Adipic\; dihydrazide\; (Hooc-Ch2\; (NH₂-NH₂)$

   Adipic acid (hooc-CH2 -CH--CH2 -COOD -COOH) + 2hyDrazine (NH2 -NHHINE (NH2 -NHH2) → Adipic dihydrazide (hooc-ch2 -ch -CHYDRAZIDE (HOOC-CH2 -CH2-NH2

2. Ukuhlambululela: Ngemuva kokusabela,Adipic dihydrazidekuhlanjululwa kabusha ngeRecrystallization noma ezinye izindlela zokususa noma iyiphi i-hydrazine noma ama-byproducts.

4. Izicelo ze-adipic dihydrazide

Adipic dihydrazideisebenzisa okuningi okubalulekile kuukuhlanganiswa kwamakhemikhali, Amakhemikhali, i-polymer chemistry, futhi nokuningi:

a. I-polymer kanye nokukhiqizwa kwe-resin

I-ADH isetshenziswa kaningi kuSynthesis of polyurethanes, ama-epoxy resins, nezinye izinto ze-polymeric. Amaqembu e-Hydrazide e-ADH akwenze kube okusebenzayoUmenzeli oxhumanisayo, ngconoIzakhiwo zemishinina-ukuqina okushisayoyama-polymers. Ngokwesibonelo:

• I-Polyurethane Coatings: I-ADH isebenza njenge-hardener, ithuthukisa ukuqina kanye nokumelana kwezimbozo.
• I-Polymer Cross-LickingE-Polymer Chemistry, i-ADH isetshenziselwa ukwakha amanethiwekhi wama-polymer amaketanga, ethuthukisa amandla kanye nokuqina.

b. Imboni yezemithi

Kuimboni yezemithi, I-ADH isetshenziswa njenge-angaphakathiekuhlanganiseni kwezimpawu ezi-bioactive.Ama-hydrazines, ezisuselwa kuma-hydrazides afana ne-ADH, zaziwa ngazoumsebenzi wemvelo, kufaka phakathi:

• Ukulwa nokuvuvukala
• Awanceli
• Antimicrobializakhiwo. I-ADH idlala indima ebalulekile ekutholweni kwezidakamizwa futhiamakhemikhali okwelapha, ukusiza ukuklama ama-ejenti amasha wezokwelapha.

c. Ama-Agrochemicals

I-adipic dihydrazide ingaqashwa ekukhiqizweni kweama-herbicides, ama-insecticides, futhiisikhuntana. I-Compound isetshenziselwa ukudala imikhiqizo ehlukahlukene ye-agrochemical evikela izilimo ezinambuzaneni nasezifo.

d. Imboni yendwangu

Kuimboni yendwangu, I-ADH isetshenziswa ekukhiqizweni kwemicu nezindwangu eziphakeme. Kusetshenziselwa uku:

• Ukuthuthukisa amandla e-fiber: Amaketanga e-ADH Cross-Links e-polymer emiculweni, ethuthukisa izakhiwo zawo zemishini.
• Thuthukisa ukumelana ukuze ugqoke: Izindwangu ziphathwe nge-ADH ExILUPET RETALUNT, YENZA ZIZOBALULEKILE KWAMAHHALA WE-HEAVE-DOUDE.

e. Ukumboza nopende

KuImikhakha kanye nopende imboni, I-ADH isetshenziswa njengeUmenzeli oxhumanisayoukwenza ngcono ukusebenza kwamapende nezimbobo. KuthuthukisaUkumelana Kwamakhemikhali, ukuqina okushisayo, futhiukuqinawezimbozo, ezibenza zilungele izimo ezinokhahlo ezifanaizimotona-Izicelo zezimboni.

f. Ucwaningo Nentuthuko

I-ADH nayo isetshenziswa ngaphakathiama-laboratories acwaningaukuhlanganisa amakhompiyutha amasha nezinto zokwakha. Ukuguquguquka kwayo okuphakathi nendawo ngaphakathisynthesis ye-organickwenza kube yigugu ekuthuthukisweni:

• Amakhompiyutha asuselwa ku-Hydrazone
• Izinto zenoveliNgezakhiwo ezihlukile
• Ukusabela okusha kwamakhemikhalikanye nezindlela zokwenziwa.

I-5. Ukuphepha nokusingathwa kwe-adipic dihydrazide

Njengamakhemikhali amaningi,Adipic dihydrazidekufanele iphathwe ngokuqapha, ikakhulukazi ngesikhathi sokuhlanganiswa kwayo. Amaphrothokholi okuphepha kumele alandelwe ukuvikela noma yiziphi izingozi ezihambisana nokusetshenziswa kwazo:

• Imishini yokuzivikela (i-PPE): Gqoka amagilavu, ama-goggles, kanye namajazi welebhu ukugwema ukubonwa kwesikhumba namehlo.
• Umoya omncane: Sebenza nge-ADH endaweni enomoya owanele noma i-fume hood ukugwema ukuzungeza noma yimaphi ama-varors noma uthuli.
• Ukubeka: Gcina i-ADH endaweni epholile, eyomile, kude nemithombo yokushisa kanye nezinto ezingahambelani.
• Ukulahlwa: Lahla i-adh ngokuya ngemithetho yendawo nokuphepha kwemvelo ukugwema ukungcoliswa.

Adipic dihydrazide(ADH) I-Chemictical Chemical ebalulekile esetshenziswa ezimbonini ezahlukahlukene, kufaka phakathiAmakhemikhali, ezolimo, izindwangu, ukumboza, futhii-polymer chemistry. Ukuvuselelwa kwayo okuguquguqukayo, ikakhulukazi ngenxa yokuba khona kwamaqembu asebenza nge-hydrazide, kwenza kube yindawo ebalulekile yokwakha yokwakha amakhemikhali ahlukahlukene, izinto zokwakha, kanye nezithako ezenziwa ngemithi ezisebenzayo.

Njengoba bobabili aUmenzeli oxhumanisayona--angaphakathiNgokwesimo se-organic, adH iyaqhubeka nokudlala indima enkulu ekwakheni ubuchwepheshe obusha nezinto zokwakha, okwenza kube yingxenye yentshisekelo enkulu kuyo yonke imikhakha eminingi.
