Āhuatanga ahupūngao:
1. Te wai kore tae me te irirangi.
2. Ira whakarewa 16.6 ℃; ira kohua 117.9 ℃; Ira hiko: 39 ℃.
3. Ko te wai whakarewa, te waiwaro, te benzene me te ethyl ether e kore e taea te rewa, e kore e rewa ki te waro disulphide.
Rokiroki:
1. Ka rongoa i roto i te whare putunga hauhautanga, whai hau.
2. Kia matara atu i te ahi, wera. Ko te wa makariri kia mau tonu te pāmahana ki runga ake i te 16 DEG C, kia kore ai e pakari. I te wa makariri, me pupuri tonu te pāmahana ki runga ake i te 16 DEG C kia kore ai e pakari.
3. Kia hiritia te ipu. Me wehe mai i te hāora me te alkali. Me karohia te whakaranu i nga tikanga katoa.
4. Whakamahi rama pahū-aru, whakaurunga ventilation.
5. Ko nga taputapu miihini me nga taputapu e aukati ana i te whakamahi ngawari ki te whakaputa korakora.
6. Me whakauru nga waahi rokiroki ki nga taputapu maimoatanga ohorere me nga taonga whare e tika ana.
Whakamahia:
1.Derivative:Te nuinga whakamahia i roto i te synthetising acetic anhydride,acetic ether,PTA,VAC/PVA,CA,etheone,chloroacetic acid,etc
2.Pharmaceutical:Wakawa acetic rite whakarewa me pharmaceuticalraw rauemi, te nuinga whakamahia mo te hanga o te penicilin G pāhare-hau, penicilin G konutai, penicillin procaine, acetanilide, sulfadiazine, me te sulfamethoxazole isoxazole, norfloxacin, ciprofloxacin, acetyl pnisenalic acid. , kawheine, etc.
3.Intermediate: acetate, konutai hauwai di, waikawa peracetic, etc
4.Wakano me te kakano tā me te tae: te nuinga whakamahia i roto i te whakaputa marara waikano me vat waikano, me te pueru tā me te tukatuka tae
5. Hangaia te haukini: I te ahua o te cuprammonia acetate, ka whakamahia ki te whakamahine i nga syngas hei tango i te iti CO me te CO2
6. Whakaahua: Kaihanga
7. rapa tūturu: Coagulant
8. Ahumahi hanga: Te aukati i te raima mai i te tio9. I roto i te addtin e whakamahia nuitia ana i roto i te maimoatanga wai, synthetic fiber, pesticides, kirihou, hiako, peita, tukatuka whakarewa me te ahumahi rapa.
Tuatahi, he rereke te ahua
1, te waikawa ahetiki tio: he waikawa ahetiki anhydrous, ko te waikawa ahetiki tetahi o nga waikawa waro nui, nga pūhui waro.
2, waikawa acetic: he waikawa monic waro, te waahanga matua o te winika.
Tuarua, nga ahuatanga rereke
1, waikawa ahetiki hukapapa: ka whakamaroke ki te hukapapa i te iti o te pāmahana, e mohiotia ana ko te waikawa acettic glacial. Ko te roha o te rōrahi i te wā whakamaroke ka pakaru pea te ipu. Ko te tohu uira ko 39 ℃, ko te rohe pahūtanga ko 4.0% ~ 16.0%, a ko te nui o te kukū e whakaaetia ana i te rangi e kore e neke atu i te 25mg/m3. Ko te waikawa ahetiki parakore ka whakatio ki roto i nga kiripiri rite-tio i raro i te ira whakarewa, na reira ka kiia ko te waikawa acettic anhydrous te waikawa acetic glacial.
2, waikawa ahetiki: kei roto ko te 98% te waikawa acetic glacial, te kiato whanaunga (he 1 te wai): 1.050; Viscosity (mPa.s): 1.22 (20 ℃); Te pehanga kohu i te 20 ℃ (KPa): 1.5; Te ahua me te hongi: He wai kore tae me te haunga waikawa ahetiki.
E toru, nga whakamahinga rereke
1, waikawa acetic huka: te nuinga whakamahia mo te kōtuitanga o te vinyl acetate, muka acetate, acetic anhydride, acetate, acetate whakarewa me te waikawa acetate halogenated. He rauemi mata nui hoki mo te rongoa, te waikano, te pesticide me etahi atu whakahiato waro.
2, te waikawa acetic: ka taea te whakamahi hei kaiwhakahaere waikawa, hei kaiwhakatikatika, hei kaihoko tiki, hei kai reka, hei mea kakara, etc.
