Kodi ma cellulose esters amapangidwa bwanji?

Ma cellulose esters ndi gulu lazinthu zomwe zimapangidwa pamene cellulose imakhudzidwa ndi asidi kapena mowa. Zotsatira zake ndizinthu zomwe zimagonjetsedwa kwambiri ndi madzi, kutentha, ndi mankhwala. Ma cellulose esters amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza zokutira, zomatira, ndi mapulasitiki.

Ma cellulose esters amapangidwa pochita ma cellulose ndi asidi kapena mowa. Zomwe zimachitika nthawi zambiri zimachitika pamaso pa chothandizira, monga sulfuric acid, komanso kutentha kwambiri. Zomwe zimapangidwira zimapanga ma esters osiyanasiyana, kutengera mtundu wa asidi kapena mowa womwe umagwiritsidwa ntchito.

Ma cellulose esters omwe amapezeka kwambiri ndi cellulose acetate, cellulose propionate, ndi cellulose butyrate. Cellulose acetate imapangidwa pamene cellulose imakhudzidwa ndi acetic acid. Cellulose propionate imapangidwa pamene cellulose imakhudzidwa ndi propionic acid. Cellulose butyrate imapangidwa pamene cellulose imakhudzidwa ndi butyric acid.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi mowa. Mowa wambiri womwe umagwiritsidwa ntchito pa izi ndi methanol, ethanol, ndi isopropanol. Zomwe zimapangidwira zimapanga ma esters osiyanasiyana, kutengera mtundu wa mowa womwe umagwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi esterifying agent, monga glycerol kapena ethylene glycol. Izi zimapanga ma ester osiyanasiyana, kutengera mtundu wa esterifying wothandizira.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi halogenating agent, monga chlorine kapena bromine. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa halogenating wothandizira.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi oxidizing agent, monga hydrogen peroxide. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa oxidizing wogwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi aminating agent, monga ammonia kapena amine. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa aminating agent omwe amagwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi chochepetsera, monga sodium borohydride kapena lithiamu aluminium hydride. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa wothandizira wochepetsera womwe umagwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi cholumikizira cholumikizira, monga dialdehyde kapena diisocyanate. Izi zimapanga ma esters osiyanasiyana osiyanasiyana, kutengera mtundu wa othandizira omwe amagwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi polymerizing agent, monga vinyl monomer kapena polyester. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa polymerizing wothandizira.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi mankhwala ochiritsa, monga epoxy kapena polyurethane. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa machiritso omwe amagwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa poyankha mapadi ndi plasticizing agent, monga phthalate kapena polyethylene glycol. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa pulasitiki wogwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi surfactant, monga nonionic kapena anionic surfactant. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa surfactant womwe umagwiritsidwa ntchito.

Ma cellulose esters amathanso kupangidwa pochita ma cellulose ndi choletsa moto, monga halogenated hydrocarbon kapena phosphorous compound. Izi zimapanga ma esters osiyanasiyana, kutengera mtundu wa retardant wamoto womwe umagwiritsidwa ntchito.

Pomaliza, ma cellulose esters amapangidwa ndikuchita cellulose ndi asidi, mowa, esterifying agent, halogenating agent, oxidizing agent, aminating agent, reduction agent, cross-linking agent, polymerizing agent, machiritso. , chopangira pulasitiki, chowotchera madzi, kapena choziziritsa moto. Mtundu wa ester wopangidwa umadalira mtundu wa reactant womwe umagwiritsidwa ntchito. Ma cellulose esters amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza zokutira, zomatira, ndi mapulasitiki.
