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

Hordhac

1,2,3,4,5-Pentamethylcyclopentadiene (sidoo kale loo yaqaan pentaheptadiene) waa unug dabiici ah. Kuwa soo socdaa waa horudhac ku saabsan hantideeda, adeegsigeeda, hababka wax-soo-saarka iyo macluumaadka badbaadada:

Tayada:

1,2,3,4,5-Pentamethylcyclopentadiene waa dareere aan midab lahayn oo leh ur gaar ah. Way ka cufan yar tahay, kuma milmi karaan biyaha, wayna ku milmi karaan dareerayaasha dabiiciga ah ee caadiga ah.

Isticmaal:

1,2,3,4,5-Pentamethylcyclopentadiene waxay leedahay codsiyo kala duwan oo duurka ku ah kimisteriga. Waxaa loo isticmaali karaa sidii qalab bilow ah iyo dhexdhexaadinta isku-dhafka dabiiciga ah ee isku-dhafka walxaha kale ee dabiiciga ah.

Habka:

1,2,3,4,5-Pentamethylcyclopentadiene waxaa lagu soo saari karaa habab kala duwan. Hababka diyaarinta caadiga ah waxaa ka mid ah kuwan soo socda:

Falcelinta iyada oo loo marayo cyclopentene: cyclopentene iyo reagents methylation (sida methyl bromide) ayaa loo isticmaalaa in lagu falceliyo xaaladaha alkaline si loo dhaliyo 1-methylcyclopentene, ka dibna 1,2,3,4,5-pentamethylcyclopentadiene waxaa lagu soo saaraa falcelinta methylation.

Fal-celinta samaynta curaarta kaarboon-kaarboon ee uu katalyeeyay biraha birta ah.

Macluumaadka Badbaadada:

1,2,3,4,5-pentamethylcyclopentadiene waxay leedahay khataro gaar ah, waxaana lagama maarmaan ah in fiiro gaar ah loo yeesho badbaadada marka la isticmaalayo. Waa kuwan qaar ka mid ah khataraha amniga ee suurtagalka ah:

Waa dareere guban kara waana in laga fogaadaa ololka furan iyo ilaha heerkulka sare.

Ka fogow in aad neefsato uumiga, ku isticmaal meel hawo fiican leh, isticmaalna qalabka ilaalinta shakhsi ahaaneed ee habboon (tusaale, ilaalinta neefsashada).

Waxay si xoog leh uga falcelin kartaa walxaha oksaydhiyeyaasha xooggan iyo acids xooggan, taasoo keenta dab ama qarax.

Fadlan si taxadir leh u shaqee marka aad isticmaalayso oo ula dhaqan si waafaqsan nidaamka hawlgalka badbaadada ee khuseeya.
