Hoʻolauna
ʻO Isoprene mercaptan kahi mea hoʻohuihui. Penei kona mau waiwai.
Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe kūlohelohe e like me nā ʻawaʻawa, eter, a me nā hydrocarbons.
2. Nā waiwai kemika: ʻO ka Isoprepent mercaptan kahi mea hoʻohaʻahaʻa loa i hiki ke hana me ka oxygen e hana i ka sulfur dioxide. Hiki ke hoʻoheheʻe ʻia e ka chlorine i ka waikona isovaleric, a i ʻole e hoʻokaʻawale ʻia e nā mea hoʻokahe i ka sulfuric acid. Loaʻa iā Isopentol ka waiwai o kahi hopena hoʻohui me nā pūhui ʻē aʻe.
Nā hoʻohana o ka isoprene mercaptan:
1. ʻO nā reagents kemika: ʻO Isopentanol kahi mea hoʻohaʻahaʻa maʻamau a me sulfiding agent, i hoʻohana nui ʻia i ka synthesis organik a me ke kemika analytical.
2. ʻAla masking agent: kona ʻala ʻala ikaika, isoprel mercaptan e hoʻohana pinepine ʻia ma ke ʻano he kemika e uhi i nā mea ʻala ʻē aʻe, e like me ka hoʻohui ʻana i kahi nui o ka isoprene mercaptan i ke kinoea maoli e uhi i ka ʻala.
Nui nā ala nui no ka hoʻomākaukau ʻana i ka isopreamyl mercaptan:
1. Hana ʻia mai ka waiʻona vinyl: hoʻomehana ʻia ka waiʻona vinyl me ka sulfur e hana i ka isopentanol.
2. Ka hoʻomākaukauʻana mai ka 15%-alcohol solution: hiki ke loaʻa ka isoprem mercaptan maʻemaʻe kiʻekiʻe ma o ka distilling, concentrating a me ka distilling i ka waiʻona a me ka hydrogen sulfide.
Pono e noʻonoʻo ʻia ka ʻike palekana i ka wā e hoʻohana ai i ka isopentanol:
1. He pilau ikaika ko Isopentan mercaptan a pono e pale aku i ka pili pono ana me ka ili, ka maka, a me ka hanu hanu. E hoʻohana i nā mea pale pilikino kūpono e like me nā mīkina lima, nā aniani, a me nā pale pale i ka wā e hoʻohana ai.
2. He wahi uila haʻahaʻa ko Isopentol a hiki ke hoʻopau ʻia, a pono e mālama ʻia mai ka ʻā a me nā wela kiʻekiʻe. Hōʻalo i ka hoʻopili ʻana me nā lapalapa ākea a i ʻole nā mea puhi ʻē aʻe.
3. ʻO ka Isopentan mercaptan he mea ia e hoʻopōʻino i ke kaiapuni a maikaʻi ʻole ka biodegradability, a ʻaʻole pono e hoʻokuʻu ʻia i loko o ke kaiapuni kūlohelohe ma ka makemake, a pono e mālama ʻia a hoʻolei ʻia e like me nā lula pili.
