Hoʻolauna
ʻO 2-Methyl-2-pentenic acid, i ʻike ʻia hoʻi he ʻakika butenedic, he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 2-methyl-2-pentenoic acid:
ʻAno maikaʻi:
- 2-Methyl-2-pentenoic acid he wai waihoʻoluʻu ʻole a ʻeleʻele melemele me ka ʻala hua.
- Hiki ke hoʻoheheʻe ʻia ka 2-Methyl-2-pentenoic acid i ka wai a me nā mea hoʻoheheʻe kūlohelohe e like me nā ʻona a me nā eter.
- He pūhui paʻa ʻaʻole ia e hoʻā wale a pahū iā ia iho i nā mahana a me nā kaomi maʻamau.
E hoʻohana:
- Hoʻohana nui ʻia ka 2-Methyl-2-pentenoic acid i ka hoʻomākaukau ʻana i nā polymers hana kiʻekiʻe e like me nā uhi kūikawā, nā adhesives, a me nā mea hoʻopaʻa.
- He monomer lua koʻikoʻi ia i hiki ke hoʻomākaukau ʻia e ka polymerization o ka butenic acid copolymers.
Hanana:
- Hiki ke hoʻomākaukau ʻia ka ʻakika 2-Methyl-2-pentenoic e ka hoʻohui ʻana i ka waikawa-catalyzed o cyclohexene.
- Hoʻopili ʻia ka Dimethyllithium a me ka cyclohexene e loaʻa ai ka 2-methyl-1-cyclohexenylmethyllithium, a laila hydrolyzed a acidified e loaʻa ai ka 2-methyl-2-pentenoic acid.
ʻIke palekana:
- ʻO ka 2-Methyl-2-pentenoic acid he mea hoʻonāukiuki i hiki ke hoʻonāukiuki i ka ʻili a me nā maka, a pono e mālama pono e like me ke komo ʻana i nā mīkina lima pale a me nā maka aniani i ka wā e hoʻohana ai.
- ʻAʻole paʻa i ka māmā a me nā wela kiʻekiʻe, a hiki i nā hopena polymerization, no laila e pale ʻia ka lōʻihi o ka ʻike ʻana i ka lā a i ʻole ka waiho ʻana i nā wela kiʻekiʻe.
- I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e mālama ʻia mai nā mea hiki ke ahi a me nā mea hoʻoheheʻe i mea e pale ai i ke ahi a pahū paha.
- I ka lawelawe ʻana i ka 2-methyl-2-pentenoic acid, pono e hahai ʻia nā protocol hoʻokolohua kūpono a me nā alakaʻi hana palekana. Inā loaʻa kahi pōʻino, pono e lawe koke ʻia nā hana pilikia kūpono a pono e ʻimi koke i ke kōkua lapaʻau ʻoihana.
