Isingeniso

I-N-vinylcaprolactam iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwe-N-vinylcaprolactam:

 

Ikhwalithi:

I-N-vinylcaprolactam iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elingavamile.

 

Sebenzisa:

I-N-vinylcaprolactam inezinhlobonhlobo zezicelo embonini yamakhemikhali. Kuyinto ebalulekile yokwenziwa, engasetshenziswa njenge-monomer yama-polymers, i-catalyst yokusabela kwe-polymerization, impahla eluhlaza yama-surfactants nama-plasticizers. Ingasetshenziswa nasezindaweni ezinjengama-coatings, oyinki, odayi, kanye nerabha.

 

Indlela:

Indlela evamile yokulungiselela i-N-vinylcaprolactam itholakala ngokusabela kwe-caprolactam ne-vinyl chloride ngaphansi kwezimo ze-alkaline. Izinyathelo eziqondile ziwukuncibilikisa i-caprolactam ku-solvent efanelekile, engeza i-vinyl chloride kanye ne-alkaline catalyst, nokushisa ukusabela kwe-reflux isikhathi esithile, futhi umkhiqizo ungatholakala ngokukhipha isiraphu noma ngokukhipha.

 

Ulwazi Lokuphepha:

I-N-vinylcaprolactam ingase icasule isikhumba namehlo ngaphansi kwezimo ezithile, futhi kufanele ihlanzwe ngamanzi amaningi ngokushesha ngemva kokuxhumana. Lapho usebenzisa futhi uphatha inhlanganisela, kuyadingeka ukuthi ugqoke izinto zokuzivikela ezifanele njengamagilavu, izibuko, nezingubo zokuzivikela ukuze kuqinisekiswe indawo yokusebenza enomoya omuhle. Kufanele igcinwe endaweni epholile, eyomile, kude nomlilo nezinto ezivuthayo. Ngesikhathi sokusebenzisa nokugcina, sicela ulandele izinqubo ezifanele zokusebenza zokuphepha nemihlahlandlela.
