2-(4-Methyl-5-thiazolyl)ethyl hexanoate (CAS#94159-32-7)
Nhanganyaya
4-Methyl-5-thiazolylethanol hexanoate, inozivikanwawo seMTBE (Methyl tert-butyl ether), imvura isina ruvara ine kunhuhwirira kwakakosha. Iyi inotevera sumo kune hunhu hwayo, kushandiswa, nzira yekugadzira uye ruzivo rwekuchengetedza:
Hunhu:
Inonyungudika mune zvakawanda organic solvents senge madoro, ether, uye ketones, asi inenge isinganyungudika mumvura.
MTBE ine yakakwira anti-kugogodza kuita uye inogona kushandiswa senge antiknock agent yepeturu.
Shandisa:
MTBE inonyanya kushandiswa sechinhu chinowedzera peturu kuwedzera kugogodza kwepeturu, kunatsiridza kupisa kwepeturu uye kuderedza kusvibiswa kwemhepo.
Inogona zvakare kushandiswa sechinhu chinonyungudutsa uye ine zvimwe zvikumbiro mumakemikari synthesis, kuongororwa kwemakemikari uye mamwe minda.
Nzira:
Kugadzirira kweMTBE kunowanzo kuwanikwa nekugadzirisa kwekugadzirisa isopropanol uye methanol pasi pemamiriro e acidic. Matanho chaiwo anosanganisira kuita isopropanol nemethanol pamberi peiyo acid catalyst (semuenzaniso, sulfuric acid) kugadzira MTBE, iyo inonatswa nedistillation kuti iwane chigadzirwa chekupedzisira.
Zvekuchengetedza
MTBE imvura inopfuta ine yakaderera flash point uye autoignition tembiricha. Inofanira kushandiswa munzvimbo inofefetera zvakanaka, kure nemirazvo yakazaruka uye nzvimbo dzinopisa.
Kuratidzwa kwenguva refu kuMTBE vapor kunogona kuve nemhedzisiro inoshatirisa pamhepo yekufema, maziso, uye ganda. Midziyo yekuzvidzivirira yakafanira senge dziviriro yekufema, magirazi uye magirovhosi ekudzivirira anofanira kupfekwa.
MTBE ine chepfu yakaderera, asi haifanirwe kumwiwa kana kubatwa nenhengo dzemukati. Kana ukapinzwa netsaona kana kubata, tsvaga kurapwa nekukasika.
