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

Gabatarwa

1,2,3,4,5-Pentamethylcyclopentadiene (wanda kuma aka sani da pentaheptadiene) wani fili ne na kwayoyin halitta. Mai zuwa shine gabatarwa ga kaddarorin sa, amfaninsa, hanyoyin masana'anta da bayanan aminci:

inganci:

1,2,3,4,5-Pentamethylcyclopentadiene ruwa ne mara launi tare da wari na musamman. Yana da ƙasa mai yawa, maras narkewa a cikin ruwa, kuma mai narkewa a cikin kaushi na gama gari.

Amfani:

1,2,3,4,5-Pentamethylcyclopentadiene yana da aikace-aikace da yawa a fagen ilimin sunadarai. Ana iya amfani da shi azaman kayan farawa da tsaka-tsaki a cikin haɗin gwiwar kwayoyin halitta don haɗuwa da sauran kwayoyin halitta.

Hanya:

1,2,3,4,5-Pentamethylcyclopentadiene ana iya haɗa shi ta hanyoyi daban-daban. Hanyoyin shiri gama gari sun haɗa da:

Amsa ta hanyar cyclopentene: cyclopentene da methylation reagents (irin su methyl bromide) ana amfani da su don amsawa a ƙarƙashin yanayin alkaline don samar da 1-methylcyclopentene, sa'an nan kuma 1,2,3,4,5-pentamethylcyclopentadiene an haɗa shi ta hanyar methylation dauki.

Halin samuwar carbon-carbon bond wanda wani karfe mai kara kuzari ya karu.

Bayanin Tsaro:

1,2,3,4,5-pentamethylcyclopentadiene yana da wasu haɗari, kuma wajibi ne a kula da aminci lokacin amfani da shi. Ga wasu haɗarin tsaro masu yuwuwa:

Ruwa ne mai ƙonewa kuma yakamata a kiyaye shi daga buɗewar wuta da maɓuɓɓugan zafin jiki.

Guji shakar tururinsa, yi amfani da su a wurin da ke da isasshen iska, da amfani da kayan kariya masu dacewa (misali, kariya ta numfashi).

Yana iya mayar da martani da ƙarfi tare da masu ƙarfi mai ƙarfi da acid mai ƙarfi, yana haifar da wuta ko fashewa.

Da fatan za a yi aiki tare da taka tsantsan lokacin amfani da kuma rike shi daidai da matakan aiki na aminci masu dacewa.
