1-Butanol

CAS 71-36-3

Cov khoom siv lub cev thiab tshuaj lom neeg

n-Butanol, tseem hu ua 1-butanol lossis butanol, yog ib hom cawv. Txhua lub molecule muaj plaub lub carbon atoms thiab nws cov mis molecular yog CH3CH2CH2CH2OH. Muaj peb lub isomers, uas yog isobutanol, sec-butanol thiab tert-butanol. Nws yog ib qho kua tsis muaj xim nrog ntxhiab cawv ntawm chav tsev kub. Nws lub ntsiab lus kub yog 117.7 ° C, qhov ceev (20 ° C) yog 0.8109g / cm3, qhov chaw khov yog -89.0 ° C, qhov chaw ci ntsa iab yog 36 ~ 38 ° C, thiab qhov chaw pib hluav taws xob yog 689F. Refractive index Chemicalbook (n20D) yog 1.3993. Nws solubility hauv dej ntawm 20 ° C yog 7.7% (qhov hnyav), thiab nws solubility hauv n-butanol yog 20.1% (qhov hnyav). Nws yog miscible nrog ethanol, ether thiab ntau lwm yam organic solvents. Nws cov pa ua rau muaj kev sib xyaw ua ke nrog huab cua, thiab nws qhov kev txwv tawg yog 3.7% ~ 10.2% (feem ntim). Butanol yog cov khoom siv raw rau kev tsim cov yas dibutyl phthalate, thiab kuj siv los ua cov kuab tshuaj rau butyl acrylate, butyl acetate, thiab ethylene glycol butyl ether.

Siv

N-Butanol feem ntau yog siv los ua phthalic acid, dibutyl phthalate, aliphatic dibasic acid thiab n-butyl ester plasticizers ntawm phosphoric acid, uas yog siv dav hauv ntau yam yas thiab roj hmab. Nws tseem yog cov khoom siv raw rau kev ua butyraldehyde, butyric acid, butyl acetate, butylamine Chemicalbook thiab butyl lactate hauv organic synthesis. Nws kuj yog ib qho extractant rau kev tsim cov melamine resin, acrylic acid, roj, tshuaj (xws li tshuaj tua kab mob, cov tshuaj hormones thiab cov vitamins) thiab cov txuj lom, thiab ib qho additive rau alkyd resin coatings. Nws kuj tseem siv tau ua cov kuab tshuaj rau cov organic dyes thiab cov number case luam ntawv, ib qho dewaxing agent, thiab lwm yam.
