Physicochemical zog:
1. Colorless kua thiab irritating dour.
2. Melting point 16.6 ℃; boiling point 117.9 ℃; Kev kub ceev: 39 ℃.
3. Solubility dej, ethanol, benzene thiab ethyl ether immiscible, insoluble hauv carbon disulphide.

Cia:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Cia kom deb ntawm qhov hluav taws kub, cua sov. Lub caij txias yuav tsum tswj qhov kub siab tshaj 16 ° C, kom tsis txhob muaj kev sib zog. Thaum lub caij txias, qhov kub yuav tsum tau khaws cia siab tshaj 16 ° C los tiv thaiv / tsis txhob khov.
3. Khaws lub thawv kaw. Yuav tsum tau sib cais los ntawm oxidant thiab alkali. Kev sib tov yuav tsum zam los ntawm txhua txoj kev.
4. Siv lub teeb pom kev tawg, qhov chaw ua pa.
5. Cov cuab yeej siv tshuab thiab cov cuab yeej uas txwv tsis pub siv yooj yim los tsim cov nplaim taws.
6. Cov chaw khaws cia yuav tsum tau nruab nrog cov cuab yeej kho mob xwm txheej ceev thiab cov khoom siv vaj tse tsim nyog.

Siv:

1.Derivative: Mas siv nyob rau hauv synthetising acetic anhydride, acetic ether, PTA, VAC / PVA, CA, ethenone, chloroacetic acid, thiab lwm yam
2. Pharmaceutical: Acetic acid ua kuab tshuaj thiab tshuaj raw cov ntaub ntawv, feem ntau yog siv rau zus tau tej cov penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfamethoxazole, thiab sulfamethoxazole isoxazole, norfloxacin, ciprofloxacin, licacetylephenone salicylic acid. caffeine, thiab lwm yam.
3.Intermediate: acetate, sodium hydrogen di, peracetic acid, thiab lwm yam
4.Dyestuff thiab textile printing thiab dyeing: Feem ntau yog siv los tsim disperse dyes thiab vat dyes, thiab textile printing anddyeing processing
5. Synthesis ammonia: Nyob rau hauv daim ntawv ntawm cuprammonia acetate, siv nyob rau hauv refining syngas kom tshem tawm ib tug litl CO thiab CO2.
6. Duab: Tus tsim tawm
7. Ntuj roj hmab: Coagulant
8. Kev tsim kho kev lag luam: Tiv thaiv pob zeb los ntawm frezing9. Hauv addtin kuj tau siv dav hauv kev kho dej, hluavtaws fiber, tshuaj tua kab, yas, tawv, xim, hlau ua thiab roj hmab kev lag luam

Lub Hoobkas muaj zog-5Disperse dyes yog siv txhua hnub, tab sis koj tuaj yeem hais tam sim ntawd, vim li cas thiaj li disperse dyes ntxiv glacial acetic acid los kho PH? (Tam sim no cov organic acids tau ntxiv los kho PH, tshwj tsis yog alkaline disperse staining.)

Yog vim li cas:

Lub stability ntawm disperse dyes nyob rau hauv dye da dej yog ze ze rau tus nqi pH. Tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias siab, yog hais tias tus nqi pH ntawm cov dye da dej tsis nruj me ntsis tswj, nws yuav feem ntau ua rau variation ntawm lub teeb xim, lub ntsiab yog vim li cas raws li nram no.

(1) Ua kom ceev hydrolysis ntawm disperse dyes, nyob rau hauv tus txheej txheem ntawm dye manufacturing, feem ntau ntxiv ib tug loj tus naj npawb ntawm dispersant, xws li diffuser NNO, lignin, sodium carbonate, thiaj li hais tias cov tshuaj zas zas tsis muaj zog alkaline,
Thaum dyeing ntawm 130% kub, nws yog ib qho yooj yim rau hydrolyze, ua rau lub teeb xim thiab faint light.
(2) Vim qhov txo qis decomposition ntawm disperse dyes, poob ntawm cov plaub hau hauv paus pawg, qhov tshwm sim no feem ntau nyob rau hauv cov qauv azo dyes.
(3) Cov phenolic pawg nyob rau hauv cov qauv molecular ntawm dyes ua rau ionic cov tshuaj tiv thaiv vim kev ua ntawm alkali, thiab cov dej solubility yog txhim khu kev qha, thaum lub dyeing sab sauv yog tsis muaj zog correspondingly. Feem ntau, cov kua dispersing ntawm dyes yog qaug zog alkaline vim qhov sib ntxiv ntawm dispersant hauv da dej dyeing.
