ʻIkepili
ʻO P-hydroxypropionone, i ʻike ʻia ʻo 3-hydroxy-1-phenylpropiotone a i ʻole vanillin, he mea hoʻohui. ʻO kēia ka wehewehe ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
ʻO ka hydroxypropiophenone he aniani paʻa, maʻamau keʻokeʻo a i ʻole melemele māmā i ke kala. He ʻala ʻono kona a hoʻohana pinepine ʻia i mea ʻala. He kiʻekiʻe ka hoʻoheheʻe ʻana o kēia pūhui ma ka lumi wela a hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik he nui.
E hoʻohana:
Hanana:
Hoʻomākaukau pinepine ʻia ka P-hydroxypropion e ka synthesis kemika. Loaʻa kahi ala maʻamau e ka esterification o ka cresol a me ka acetone, a ukali ʻia e ka desulfation ma ka hoʻomehana ʻana i nā huahana esterification.
ʻIke palekana:
ʻO ka Hydroxypropiophenone ka mea maʻamau i manaʻo ʻia he pūhui palekana. Hiki i ka hoʻolaha nui ʻana ke hoʻonāukiuki i ka ʻili a me ka maka. Pono e mālama ʻia e like me nā mīkina lima, nā maka aniani, a me nā lole hana kūpono ke hoʻohana a lawelawe ʻia paha. E hōʻalo i ka hanu ʻana i kona lepo a i ʻole nā huhū a e hōʻoia i ka hana ʻana ma kahi wahi me ka makani. Inā ʻai ʻia a ʻike ʻia paha, e ʻimi koke i ka lāʻau lapaʻau.
