Taw qhia
Tosylisocyanate, tseem hu ua Tosylisocyanate. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm p-toluenesulfonylisocyanate:
Zoo:
- Cov tsos mob: tsis muaj xim lossis lub teeb daj ua kua.
- Solubility: Soluble nyob rau hauv cov organic solvents, xws li ethanol, dimethylformamide, thiab lwm yam.
- Kev ruaj ntseg: ruaj khov, tab sis kev sib cuag nrog dej thiab muaj zog alkalis yuav tsum zam.
Siv:
Tosyl isocyanate feem ntau yog siv los ua cov tshuaj reagent lossis cov tshuaj pib hauv cov tshuaj tiv thaiv organic. Tosyl isocyanate tuaj yeem siv los ua cov khoom siv hluav taws xob thiab kev tiv thaiv hauv cov khoom siv hluav taws xob.
Txoj kev:
Txoj kev npaj ntawm toluenesulfonyl isocyanate feem ntau yog tau los ntawm reacting benzoate sulfonyl chloride nrog isocyanate. Cov kauj ruam tshwj xeeb suav nrog cov tshuaj tiv thaiv ntawm sulfonyl chloride benzoate nrog isocyanate nyob rau hauv lub xub ntiag ntawm lub hauv paus, nyob rau hauv chav tsev los yog tsis kub. Cov khoom siv tshuaj tiv thaiv feem ntau yog muab rho tawm thiab ua kom huv los ntawm txoj kev xws li kuab tshuaj extraction thiab crystallization.
Cov ntaub ntawv kev nyab xeeb:
- Kev sib cuag nrog daim tawv nqaij thiab qhov muag yuav tsum zam thaum lub sijhawm ua haujlwm kom tsis txhob muaj qhov khaus lossis raug mob.
- Qhov chaw ua haujlwm yuav tsum muaj qhov cua zoo thiab tsis txhob nqus nws cov vapors.
- Thaum lub sijhawm khaws cia thiab nqa, kev sib cuag nrog cov dej noo thiab muaj zog alkalis yuav tsum zam kom tsis txhob muaj kev cuam tshuam tsis zoo.
- Ua raws li cov txheej txheem kev nyab xeeb thiab ntsuas thiab hnav cov cuab yeej tiv thaiv tus kheej tsim nyog thaum siv thiab tuav tosyl isocyanate.
