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

Nyob rau hauv xyoo tas los no, methamphetamine yog qhov teeb meem. Cov neeg tsim khoom lag luam thiab cov chaw tsim khoom hauv ntau lub lag luam thiab cov teb tau pib yuav cov tshuaj methamphetamine ntau, uas tau ua rau kev lag luam ntawm methamphetamine sai sai thiab nthuav dav.

Raws li ib tug fatty acid uas muaj nyob rau hauv cov xwm, lyceine tsis tau tsuas yog muaj kev lag luam loj heev, tab sis kuj muaj cov organic compound nrog qaub thiab irritating tsw.

Muaj ntau tus neeg uas yuav tsum tau ua cov tshuaj methamphetamine vim tias muaj ntau thiab siv ntau ntawm cov tshuaj methamphetamine, thiab nws kuj yog qhov kev xaiv zoo tshaj plaws hauv kev tsim khoom, kev tsim khoom thiab kev ua haujlwm hauv ntau lub teb.
Yog li lo lus nug los, kev siv cov tshuaj methamphetamine yog dab tsi?

1. Nyob rau hauv lub neej niaj hnub ntawm tsev neeg, siv nws los ua ib qho kev tshem tawm cov av;

2. Nws yog siv los ua pH ntawm kev ua zaub mov thiab kev tsim khoom;

3. Hauv kev lag luam kev lag luam tshuaj tua kab, tshuaj thiab dyes, siv nws ua cov kuab tshuaj thiab cov khoom siv raw.

Ntxiv rau cov hom phiaj saum toj no, cov dej khov acetic acid kuj tseem ua lub luag haujlwm ntau hauv kev lag luam xws li hluavtaws fiber ntau thiab dyeing thiab weaving.

Txawm li cas los xij, txoj hauv kev zoo siab tshaj plaws yog suav cov ntawv thov ntawm cov dej khov cinemic acid hauv kev tsim cov kua txiv hmab txiv ntoo thiab cov kab mob edible:

1. Vinegar ntau lawm:

Qhov tsim nyog siv cov dej khov acetic acid hauv kev tsim cov kua txiv hmab txiv ntoo tuaj yeem tsis tsuas yog pab cov tuam txhab txo cov nqi ntawm cov kua txiv hmab txiv ntoo, tab sis kuj txhim kho qhov zoo ntawm vinegar, ua kom cov khoom tswj tau yooj yim dua, yooj yim, thiab txhim khu kev lag luam kev sib tw ntawm vinegar;
