Taw qhia
Methyl furfuryl sulfide, tseem hu ua methyl sulfide los yog thiomethyl ether, yog cov organic compound.
Cov khoom siv tshuaj lom neeg: Methyl furfuryl sulfide yog ib qho kev txo qis uas tuaj yeem hnov mob nrog oxygen lossis halogens. Nws tuaj yeem ua rau muaj kev cuam tshuam nucleophilic ntxiv nrog cov tebchaw xws li aldehydes, ketones, thiab lwm yam.
Kev siv tseem ceeb ntawm methylfurfuryl sulfide muaj xws li:
Raws li cov kuab tshuaj: Methyl furfuryl sulfide tuaj yeem siv los ua cov kuab tshuaj hauv cov organic synthesis tshuaj los txhawb cov tshuaj tiv thaiv.
Photosensitizer: Methyl furfuryl sulfide kuj tseem siv tau los ua cov photosensitizer, uas muaj cov ntawv thov hauv cov ntaub ntawv photosensitive, thaij duab thiab luam ntawv.
Txoj kev npaj ntawm methyl furfuryl sulfide feem ntau tau txais los ntawm ob txoj kev:
Direct synthesis method: tau los ntawm cov tshuaj tiv thaiv ntawm methyl mercaptan thiab methyl chloride.
Txoj kev tawm ntawm cov tshuaj tiv thaiv: tau los ntawm reacting thioether nrog alkaline cawv, thiab ces reacting nrog methyl chloride.
Methylfurfuryl sulfide ua rau khaus thiab ua rau khaus ntawm lub qhov muag thiab tawv nqaij, thiab cov khoom siv tiv thaiv yuav tsum tau hnav thaum tuav kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
Thaum khaws cia thiab siv methyl furfuryl sulfide, tsis txhob sib cuag nrog cov neeg muaj zog oxidizing xws li oxygen thiab halogens los yog cov khoom siv hluav taws xob kom tsis txhob muaj kev phom sij txaus ntshai.
Tsis txhob nqus cov vapors ntawm methylfurfuryl sulfide thiab ua haujlwm hauv qhov chaw uas muaj cua zoo nrog kev tiv thaiv ua pa.
Tsis txhob tso cov tshuaj methylfurfuryl sulfide rau hauv cov dej los yog cov dej ntws kom tsis txhob muaj kuab paug rau ib puag ncig.
