tert - butyl acetate usage thiab synthesis
|
Tshuaj Tshuaj Muaj Zog |
TERT - butyl acetate los yog t- butyl acetate kua nrog lub camphoror blueberry {2} zoo li tsw. Nws yog siv los ua cov kuab tshuaj nyob rau hauv kev tsim cov lacquers, enamels, inks, cov nplaum, nyias, thiab cov tshuaj ntxuav. Nws tseem raug siv los ua kev ntxiv los txhim kho cov khoom tiv thaiv antiknock ntawm lub cev muaj zog roj. TERT - butyl acetate muaj peb isomners: n} butyl acetate, thiab sec- butyl acetate. |
|
Cov Khoom Siv Lub Cev |
Tsis muaj kob kua nrog lub fruity tsw. Cov ntxhiab thesel confentration hauv dej yog 4 ppm (Chris, 1994). Nagata thiab Searuchi (1990) tau tshaj tawm cov ntxhiab uas muaj ntxhiab tsw ntawm 71 ppbv. |
|
Kev siv |
tert - butyl acetate yog cov kuab tshuaj muaj nyob rau hauv kev ua yeeb yam, tawv tawv, airplane dope, tshuaj tsw qab, thiab ua khoom noj ntxiv. |

chaw ntim khoom |
TERT - butyl acetate yuav tsum tau muab cia rau hauv thaj chaw txias, zoo} pa taws qhov chaw nyob hauv cov ntawv sau ruaj ruaj uas muaj cov qauv kev cai. Ntim ntawm Tert Butetate yuav tsum tau tiv thaiv los ntawm kev puas tsuaj rau lub cev thiab yuav tsum tau khaws cia cais tawm ntawm nitrates, muaj zog alkalis, tshav kub, txim taws, thiab qhib nplaim taws. Vim tias cov ntim uas yav dhau los muaj tert {{4 4}} butyl acetate tseem yuav tuav cov khoom resi dues, lawv yuav tsum tau ua haujlwm kom tsim nyog |

Khaws rau hauv qhov chaw txias, tshuab ua kom muaj zog. Tseg deb ntawm hluav taws thiab cov khoom cua sov. Qhov ntsuas kub yuav tsum tsis pub tshaj 37 degree. Khaws lub thawv ntim kaw kom nruj. Nws yuav tsum tau muab cais cais los ntawm oxidants, acids, thiab alkalis, thiab zam kev sib xyaw. Siv tawg - ein proving teeb pom kev zoo thiab cov chaw ua pa. Nws yog txwv tsis pub siv cov khoom siv txhua yam thiab cov cuab yeej uas yooj yim tsim cov txim taws. Cov chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kub ceev thiab cov khoom siv cia khoom haum.
Kev daws teeb meem
1. Acetic Ahanrifia txoj kev: sib xyaw tert - befrux rau 2h, tom qab ntawd txias kom txog rau dej, thiab tom qab ntawd ntxuav nws nrog 10% potassium carbonate. Nws tuaj yeem qhuav nrog anhydroary carbonate, thiab tom qab ntawd distilled kom sau 95 ~ 96℃distillate kom tau cov khoom tiav.
2. Acetyl chloride txoj kev: sib xyaw tert - Defux ceev, tswj hwm lub ntsej muag pub kub, n} {- dimethylandaniline Hydrochloride yog crystallized, txias rau hauv ib lub da dej khov, thiab tom qab ntawd rhuab rau 1h. Ntxiv cov dej kom yaj tag nrho cov khib nyiab, muab rho tawm nrog txias, ntxuav ib zaug, kom qhuav sodium, thiab ua kom tau cov khoom tiav.
