Intshayelelo
i-pent-4-ynoic acid, eyaziwa ngokuba yi-pent-4-ynoic acid, i-chemical formula C5H6O2. Oku kulandelayo kukwazisa ngobume, ukusetyenziswa, ukuqulunqwa kunye nolwazi olukhuselekileyo lwe-pent-4-ynoic acid:
Indalo:
- pent-4-ynoic acid lulwelo engenambala kunye nevumba elibukhali.
-Ubunzima bayo bemolekyuli yi-102.1g/mol.
Sebenzisa:
- i-pent-4-ynoic acid yinto ebalulekileyo ephakathi kwi-chemical synthesis kwaye isetyenziselwa ukulungisa ezinye iikhompawundi.
-Ingasetyenziselwa i-carbonylation reaction, i-condensation reaction kunye ne-esterification reaction kwi-organic synthesis reaction.
I-pent-4-ynoic acid ingasetyenziselwa ukulungiswa kweziyobisi, iziqholo kunye nedayi.
Indlela yokulungiselela:
-Ukulungiswa kwe-pent-4-ynoic acid inokufumaneka nge-1-chloropentyne kunye ne-acid hydrolysis. Okokuqala, i-1-chloropentyne iphendulwa ngamanzi ukunika i-aldehyde ehambelanayo okanye i-ketone, kwaye ke i-aldehyde okanye i-ketone iguqulwa ibe yi-pent-4-ynoic acid nge-oxidation reaction.
Ulwazi ngoKhuseleko:
- i-pent-4-ynoic acid yikhemikhali ecasulayo enokubangela ukucaphuka kunye nokuvuvukala ngokudibana nolusu kunye namehlo.
-Nxiba iiglavu zokukhusela, iiglasi, kunye nempahla yaselabhoratri xa usebenzisa i-pent-4-ynoic acid.
-Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango.
-Gwema ukudibanisa ne-oxidants, i-acids eqinile kunye neziseko ezinamandla ngexesha lokugcinwa kunye nokusetyenziswa ukuphepha ukuphendula okuyingozi.
Nceda uqaphele ukuba ngaphambi kokusebenzisa nayiphi na ikhemikhali, kufuneka ufunde i-data sheet yokhuseleko (MSDS) yekhemikhali ngononophelo kwaye ulandele iindlela zokusebenza ezichanekileyo kunye neenkqubo zokusebenza ezikhuselekileyo.
