Heptane (CAS#142-82-5)

tayada
dareere aan midab lahayn. Aan biyo ku milmin, ku milmin alkohol, micible ether, chloroform. Uumigeedu waxa uu sameeyaa hawo isku dhafan oo qarxa, kaas oo sababa gubasho iyo qarax haddii uu jiro olol furan iyo tamar kuleyl sare leh. Waxay si adag uga falcelin kartaa oksaydhiyeyaasha.

Habka
Heerka warshadaha n-heptane waxaa lagu nadiifin karaa dhaqidda aashitada sulfuric ee xoogga leh, nadiifinta azeotropic methanol iyo habab kale.

isticmaal
Waxa loo istcimaalaa sida reagent gorfaynta, heerka tijaabada garaaca mishiinka shidaalka, walax tixraaca falanqaynta chromatographic, iyo dareere. Waxaa loo istcimaalaa halbeeg loogu talagalay go'aaminta lambarka octane, waxaana sidoo kale loo isticmaali karaa sida maandooriyaha, dareeraha iyo alaabta ceeriin ee isku dhafka dabiiciga ah.

amniga
mouse cirbadeynta xididada LD50: 222mg/kg; mouse la nuugo 2h LCso: 75000mg/m3. Walaxdaasi waxay waxyeelo u geysataa deegaanka, waxay wasakh u keeni kartaa haadka biyaha iyo hawada, iyo bioaccumulates oo ku jira silsiladaha cuntada ee muhiimka u ah aadanaha, gaar ahaan kalluunka. Heptane waxay keeni kartaa dawakhaad, lalabo, anorexia, socod yaab leh, iyo xataa miyir beelid iyo miyir beelid. Ku kaydi bakhaar qabow oo hawo leh. Aad bay ugu nugul yihiin dabka. Ka fogow dabka iyo ilaha kulaylka. Heerkulka bakhaarku waa inuusan dhaafin 30°C. Ka ilaali iftiinka qorraxda tooska ah. Weelka si adag u xidh. Waa in lagu kaydiyaa si gooni ah oo ka baxsan wakiilka oksaydhka.
