Isingeniso
I-4-Methyl-4-(methylthio)pentane-2-one, eyaziwa nangokuthi i-MPTK, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso esinemininingwane yemvelo, ukusetshenziswa, indlela yokukhiqiza kanye nolwazi lokuphepha lwe-MPTK:
Ikhwalithi:
- Ukubukeka: I-MPTK ibonakala njengamakristalu aphuzi angenambala noma akhanyayo.
- Ukunyibilika: I-MPTK iyancibilika kwezinye izinyibilikisi zemvelo, njenge-ether ne-chloroform, kodwa ayincibiliki kahle emanzini.
Sebenzisa:
- Ukuhlanganiswa kwamakhemikhali: I-MPTK ingasetshenziswa njengendawo ephakathi kokuhlangana kwe-organic ukuze kuhlanganiswe ezinye izinhlanganisela eziphilayo.
- Ama-insecticides: I-MPTK ingasetshenziswa futhi njengento eluhlaza yezibulala-zinambuzane kwezolimo.
Indlela:
- I-MPTK ivame ukutholwa ngokusabela kwama-sulfide ane-alkyl halides. I-thioalkane ehambisanayo itholakala ngokusabela i-alkyl halide nge-metal sulfide (isb, i-sodium methyl mercaptan). Bese, ngokusabela i-thioalkane nge-acetic anhydride ne-acid chloride, umkhiqizo wokugcina we-MPTK uyakhiqizwa.
Ulwazi Lokuphepha:
- I-MPTK kufanele igcinwe kude nezinga lokushisa eliphezulu kanye namalangabi avulekile, futhi igcinwe endaweni epholile, eyomile ivalwe futhi ivalwe.
- Gqoka izinto zokuzivikela ezifanele, okuhlanganisa izibuko zamakhemikhali zokuzivikela namagilavu, lapho usebenzisa i-MPTK ukuze ugweme ukuthintana ngqo nesikhumba namehlo.
- Kufanele kuqashelwe ukugwema ukuhogela uthuli noma umhwamuko lapho ubamba i-MPTK, futhi izinsimbi zokuphefumula kufanele zigqokwe uma kunesidingo.
- Uma ungenisa ngephutha noma uthintana ne-MPTK, funa usizo lwezokwelapha futhi uphathe iphakheji noma ilebula nawe ukuze udokotela wakho akwazi ukuhlonza izithako.
