Taw qhia
6-Heptynoic acid yog cov organic compound nrog cov qauv molecular C8H12O2 thiab molecular hnyav ntawm 140.18g / mol. Cov hauv qab no yog cov lus piav qhia ntawm qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb ntawm 6-Heptynoic acid:
Xwm:
6-Heptynoic acid yog cov xim tsis muaj xim rau daj daj daj nrog cov ntxhiab tsw tshwj xeeb. Nws yog soluble hauv dej, ethanol thiab Ether solvents ntawm chav tsev kub. Cov tshuaj tuaj yeem ua rau muaj kev cuam tshuam nrog lwm cov tshuaj los ntawm nws pawg carboxylic acid.
Siv:
6-Heptynoic acid tuaj yeem siv ntau yam kev cuam tshuam hauv cov organic synthesis. Nws feem ntau yog siv los ua ib qho tseem ceeb ntawm cov organic synthesis intermediate rau kev npaj ntawm lwm cov tebchaw, xws li tshuaj, dyes thiab heterocyclic compounds. Tsis tas li ntawd, 6-Heptynoic acid kuj tuaj yeem siv rau hauv kev tsim cov coatings, adhesives thiab emulsifiers.
Txoj kev:
6-Heptynoic acid tuaj yeem npaj los ntawm reacting Heptyne nrog hydrated zinc ntsev nyob rau hauv alkaline tej yam kev mob. Ua ntej, qhov sib ntxiv ntawm Cyclohexyne thiab sodium hydroxide tov muab cyclohexynol. Tom qab ntawd, cyclohexynol hloov mus rau 6-Heptynoic acid los ntawm oxidation.
Cov ntaub ntawv kev nyab xeeb:
Thaum siv 6-Heptynoic acid, yuav tsum tau them nyiaj rau nws qhov khaus. Tsis txhob sib cuag nrog daim tawv nqaij, qhov muag thiab cov mucous daim nyias nyias. Hnav cov looj tsom iav, hnab looj tes thiab lub tsho tiv thaiv lub sijhawm ua haujlwm kom ntseeg tau tias muaj cua zoo. Yog tias noj los yog sib chwv tshwm sim, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob. Kev khaws cia yuav tsum raug kaw, kom deb ntawm hluav taws thiab tshav ntuj.
