Isingeniso
I-4-Isopropylacetophenone iyinhlanganisela yezinto eziphilayo. Okulandelayo izakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: Uketshezi olungenambala
- I-Flash Point: 76°C
- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether
- Iphunga: Ukunambitheka okubabayo, okunjengesinongo
Sebenzisa:
- I-4-Isopropylacetophenone isetshenziswa kakhulu njengesithako kumakha nama-flavour.
- Ibuye isetshenziswe emkhakheni we-chemical synthesis njenge-intermediate in organic synthesis.
Indlela:
- Indlela yokulungiselela ye-4-isopropylacetophenone ingafinyelelwa ngokusabela kwe-ketaldehyde condensation. Indlela evame ukusetshenziswa iwukusabela i-isopropylbenzene nge-ethyl acetate futhi ihlanganise, iyihlukanise futhi iyihlanze ukuze kutholwe umkhiqizo oqondiwe.
Ulwazi Lokuphepha:
- I-4-Isopropylacetophenone iwuketshezi oluvuthayo, futhi kufanele kuthathwe ukunakekelwa ukuze kugwenywe ukuthintana namalangabi avulekile kanye nezindawo zokushisa eziphakeme ngesikhathi sokugcina nokusebenzisa.
- Ukuchayeka isikhathi eside kumhwamuko noma oketshezini lwento kungase kubangele ukucasuka kwamehlo nesikhumba futhi kufanele kugwenywe.
- Gqoka amagilavu okuvikela afanele, izibuko, nezingubo zokumboza lapho usebenzisa futhi uqinisekise ukuthi usebenza endaweni enomoya omuhle.
- Ukuthobela izinqubo ezifanele zokusebenza zokuphepha kanye nemithetho ngesikhathi sokugcina nokuphatha.
