Umyalo:

Kusetshenziswa ikakhulukazi ekuhlanganisweni kwama-acrylates, ama-acrylamides, kanye naphakathi kwe-ejenti yokulwa nokuqothuka I

Ama-intermediates we-Organic synthesis. I-Monomer ye-polymer compound.

I-Acryloyl chlorideiyinhlanganisela ephilayo enezakhi zamakhemikhali ezisebenzayo. Ngenxa yekhabhoni ye-carbon carbon unsaturated double bond ne-chlorine athomu group esakhiweni samangqamuzana, ingaveza izinhlobo eziningi zokuphendula kwamakhemikhali, bese ithola izinhlobo ezahlukahlukene zezinto eziphilayo. Ngokuvamile, i-acryloyl chloride ingasetshenziswa njengezinto eziphakathi ezisetshenziswa kakhulu ku-organic synthesis, ngakho-ke umkhawulo wayo wokuphinda usebenzise mkhulu mkhulu. Uma i-acryloyl chloride iphendulwa nge-acrylamide, i-n-acetylacrylamide enenani elibalulekile lezimboni lingalungiswa.

Ukukhiqizwa indlela:

 i-acrylic acid ne-phosphorus trichloride kuyasetshenzwa, isilinganiso se-molar se-acrylic acid ne-phosphorus trichloride ngu-1: 0.333, zombili zixubene futhi zishisa ngokubila. Pholisa kancane ingxube yokuphendula ibe ngu-60-70℃. Isikhathi sokuphendula sasingu-15 min, bese kuthi isikhathi sokuphendula kwaba ngu-2 h ekamelweni lokushisa. Umkhiqizo wokuphendula utholwe nge-distillation yengxenyenamba esindayo ngaphansi kwengcindezi encishisiwe (70-30 kPa). Isivuno sasingama-66%.

Izinto ezidinga ukunakwa:

Isigaba: uketshezi oluvuthayo; Ukuhlukaniswa kobuthi: ubuthi

Amagundane adonsa i-LCLo: 25 ppm / 4H. Amagundane adonsa i-LC50: 92 mg / m3 / 2H.

Ngemuva kokuhogela i-370mg / m ^ 3 (100ppm) yamahora ama-2, amagundane akhula ukozela, i-dyspnea ne-edema yamaphaphu; ngemuva kokuhogela i-18.5mg / m ^ 3 ngamahora ama-5, izikhathi ezi-5, amagundane athuthukisa ukucasuka kwamehlo, i-dyspnea kanye nokozela; amagundane amathathu kwamane afa izinsuku ezintathu ngemuva kokuphela kocwaningo, futhi inyumoniya yatholakala ku-anatomy; ngemuva kokuhogela i-9.3mg / m ^ 3 ngamahora ayi-6, ama-3 amahlandla amathathu, elinye lamagundane ayisishiyagalombili lafa, nokuvuvukala kwamaphaphu, i-edema yamaphaphu nokuvuvukala kwatholakala ku-autopsy. Ukuhogela i-3.7 mg / m ^ 3, amahora we-6, ama-15 times, kungekho zimpawu zobuthi, i-anatomy ikhombise i-viscera ejwayelekile

Imininingwane yokucasula: unogwaja wesikhumba 10mg / 24h; unogwaja wamehlo 500mg ngokulingene.

Izici eziyingozi zeziqhumane: ukuqhuma lapho kuxutshwe nomoya

Izici ezinobungozi bokusha: ezivuthayo uma kwenzeka umlilo uvulekile, izinga lokushisa eliphakeme kanye ne-oxidant; intuthu enobuthi ye-chloride eyenziwe ngomlilo; igesi enobuthi i-hydrogen chloride ebolile uma kwenzeka kushisa.

Izici zokugcina nokuhamba: indawo yokugcina inomoya futhi yomile emazingeni aphansi okushisa; igcinwa ngokwehlukana nama-oxidants, ama-acid kanye ne-alkalis.

Ama-ejenti wokucisha: i-powder eyomile, isihlabathi esomile, i-carbon dioxide, i-foam, i-ejenti yokuqeda i-1211.

Ukupakisha: 50kg / isigubhu.

Amandla wonyaka: Amathani angama-200 / ngonyaka
