Āhuatanga matū 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 me 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. Nga taputapu miihini me nga taputapu e aukati ana i te whakamahi i nga korakora ngawari.
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.
Ka whakamahia nga waikano marara ia ra, engari ka taea e koe te kii tonu, he aha te waikano marara ki te waikawa acetic glacial hei whakatika i te PH? (Kei te taapirihia nga waikawa waro hei whakatika i te PH, haunga te tae marara kawakore)
Ko te take:
Ko te pumau o nga waikano marara i roto i te pati waikano e piri tata ana ki te uara pH. Ina koa i te teitei o te pāmahana me te pehanga teitei, mena kaore i te tino whakahaerehia te uara pH o te pati waikano, he maha nga wa ka puta te rereketanga o te marama tae, ko nga take matua e whai ake nei.
(1) Na te tere o te hauwai o nga waikano marara, i roto i te mahi hanga waikano, he maha nga wa ka taapirihia he maha o nga dispersants penei i te diffusion agent NNO, lignin, sodium carbonate, me etahi atu, kia ngoikore ai te waikano, i roto i
Ina tae ki te 130% teitei o te pāmahana, he ngawari ki te whakamaarama, ka puta he tae marama me te tae ngoikore.
(2) Na te whakahekenga o nga waikano marara, te ngaronga o te roopu chromophore, he maha nga wa kei roto i nga tae me te hanganga azo.
(3) Ko te roopu phenolic i roto i te hanganga ngota o te waikano ka puta he tauhohenga katote na runga i te mahi o te kawakawa, ka whakanuia te wairewa o te wai, ka ngoikore te tae, he maha na te taapiri o te dispersant i roto i te pati waikano. , ka puta te marara o te waikano me te kawakore ngoikore.
