Gabatarwa
pent-4-ynoic acid, kuma aka sani da pent-4-ynoic acid, sinadarai dabara C5H6O2. Mai zuwa shine gabatarwa ga yanayi, amfani, tsari da bayanan aminci na pent-4-ynoic acid:
Hali:
- pent-4-ynoic acid ruwa ne marar launi tare da ƙamshi mai ƙamshi.
-Ma'auni na kwayoyin halittar dangi shine 102.1g/mol.
Amfani:
- pent-4-ynoic acid shine muhimmin tsaka-tsaki a cikin haɗin sinadarai kuma ana amfani dashi don shirya wasu mahadi.
-Ana iya amfani dashi don amsawar carbonylation, halayen motsa jiki da halayen esterification a cikin halayen haɓakar ƙwayoyin cuta.
- pent-4-ynoic acid kuma ana iya amfani dashi a cikin shirye-shiryen magunguna, kamshi da rini.
Hanyar Shiri:
Ana iya samun shirye-shiryen pent-4-ynoic acid ta 1-chloropentyne da acid hydrolysis. Na farko, 1-chloropentyne yana amsawa da ruwa don ba da aldehyde ko ketone daidai, sa'an nan kuma aldehyde ko ketone ya canza zuwa pent-4-ynoic acid ta hanyar oxidation.
Bayanin Tsaro:
- pent-4-ynoic acid wani sinadari ne mai ban haushi wanda zai iya haifar da haushi da kumburi yayin haɗuwa da fata da idanu.
-Sanya safar hannu masu kariya, tabarau, da tufafin dakin gwaje-gwaje yayin amfani da pent-4-ynoic acid.
-Idan aka hadu da fata ko idanu, nan da nan a wanke da ruwa mai yawa sannan a nemi kulawar likita.
-A guji haɗuwa da oxidants, acid mai ƙarfi da tushe mai ƙarfi yayin ajiya da amfani don guje wa halayen haɗari.
Lura cewa kafin amfani da kowane sinadari, yakamata ku karanta takardar bayanan aminci (MSDS) na sinadari a hankali kuma ku bi ingantattun hanyoyin aiki da amintattun hanyoyin aiki.
