Hoʻolauna
ʻO ka P-hydroxyvalerone kahi mea hoʻohuihui. Eia ka wehewehe kikoʻī i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka p-hydroxypenterone:
ʻAno maikaʻi:
He wai kala ʻole ʻo P-hydroxyvalerone me kahi ʻono ʻono kū hoʻokahi. Hiki ke hoʻoheheʻe ʻia e ka wai a me nā mea hoʻoheheʻe he nui e like me ka ethanol a me ka ether.
E hoʻohana:
Hoʻohana nui ʻia ka P-hydroxyvalerone i ka ʻoihana kemika. He mea hoʻoheheʻe koʻikoʻi a hoʻohana mau ʻia i ka hoʻomākaukau ʻana i nā pena pena, nā inika a me nā varnish. Hiki ke hoʻohana pū ʻia ka P-hydroxypentanone ma ke ʻano he synthetic raw material no nā mea ʻala, e like me nā mea ʻala a me nā mea ʻono.
Hanana:
Nui nā ala e hoʻomākaukau ai i ka p-hydroxypenterone. ʻO kekahi o nā ʻano hana maʻamau ka loaʻa ʻana o ka p-hydroxypentanone ma ka hopena o ka acid-catalyzed o ka benzoic acid a me ka acetone. Loaʻa kahi ala ʻē aʻe e ka transesterification o ka benzoic acid a me ka acetone, a ukali ʻia e ka hydrolysis acid.
ʻIke palekana:
ʻO ka P-hydroxyvalerone kahi wai hiki ke hoʻomāmā a pahū paha me ka ea. I ka lawelawe ʻana a me ka hoʻohana ʻana, pono e lawe ʻia nā hana pale ahi a pale ʻia me nā lapalapa ākea a me nā kumu wela kiʻekiʻe. ʻO ka P-hydroxyvalerone ka hopena hoʻonāukiuki a me ka corrosive ma nā maka a me ka ʻili, a pono e pale ʻia ka pilina pololei. Pono e hoʻohana ʻia nā lako pale pilikino e like me nā mīkina lima a me nā maka aniani i ka wā e hoʻohana ai.
