1 2 3 4 5-Pentamethylcyclopentadiene（CAS# 4045-44-7)

Hoʻolauna

ʻO 1,2,3,4,5-Pentamethylcyclopentadiene (ʻike ʻia ʻo pentaheptadiene) he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

ʻAno maikaʻi:

ʻO 1,2,3,4,5-Pentamethylcyclopentadiene he wai kala ʻole me kahi ʻala kūikawā. He liʻiliʻi ka mānoanoa, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau.

E hoʻohana:

ʻO 1,2,3,4,5-Pentamethylcyclopentadiene ka nui o nā noi ma ke kahua o ke kemika. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka a waena i ka synthesis organik no ka synthesis o nā pūhui organik ʻē aʻe.

Hanana:

Hiki ke hoʻohui ʻia ka 1,2,3,4,5-Pentamethylcyclopentadiene e nā ʻano hana like ʻole. ʻO nā ʻano hana hoʻomākaukau maʻamau e like me kēia:

ʻO ka hopena ma o ka cyclopentene: cyclopentene a me methylation reagents (e like me methyl bromide) i hoʻohana ʻia e hana ma lalo o nā kūlana alkaline e hoʻohua i ka 1-methylcyclopentene, a laila hoʻohui ʻia ka 1,2,3,4,5-pentamethylcyclopentadiene ma o ka hopena methylation.

He hopena hoʻokumu ʻana i ke kalapona kalapona i hoʻopaʻa ʻia e ka mea hoʻoheheʻe metala.

ʻIke palekana:

ʻO 1,2,3,4,5-pentamethylcyclopentadiene kekahi mau pilikia, a pono e hoʻolohe i ka palekana i ka wā e hoʻohana ai. Eia kekahi mau pilikia palekana.

He wai ʻaʻa ia a pono e mālama ʻia mai nā lapalapa ākea a me nā kumu wela kiʻekiʻe.

E hō'ole i ka ho'ohu 'ana i kona mau mahu, e ho'ohana ia mau mea ma kahi e ho'ohehe'e maika'i 'ia, a e ho'ohana i nā lako pale pono'ī (e la'a, ka pale hanu).

Hiki iā ia ke hana me ka ikaika me nā mea hoʻoheheʻe ikaika a me nā waikawa ikaika, e hopena i ke ahi a pahū paha.

E ʻoluʻolu e hana me ka akahele ke hoʻohana a mālama iā ia e like me nā kaʻina hana palekana kūpono.
