Taw qhia
methyl hydrogen azelate, tseem hu ua polycarboxylate, yog ib qho tseem ceeb siab molecular polymer. Nws muaj cov khoom nram qab no:
1. Lub cev muaj zog: methyl hydrogen azelate yog cov kua tsis muaj xim lossis lub teeb daj, nrog cov solubility zoo, soluble hauv dej, cawv thiab cov kuab tshuaj organic.
2. Cov khoom siv tshuaj lom neeg: methyl hydrogen azelate yog ib qho ester compound nrog kev ruaj khov thiab tshuaj lom neeg. Nws tuaj yeem hydrolyzed rau azelaic acid thiab methanol.
Kev siv tseem ceeb ntawm methyl hydrogen azelate suav nrog:
1. Polymer npaj: methyl hydrogen azelate tuaj yeem ua polymerized nrog lwm cov monomers los npaj siab molecular polymers. Cov polymers no muaj cov khoom zoo heev thiab tuaj yeem siv rau hauv ntau yam lag luam xws li txheej, nplaum, yas, fibers, thiab lwm yam.
2. Surfactant: methyl hydrogen azelate tuaj yeem siv los ua emulsifier, dispersant thiab wetting agent, dav siv hauv tshuaj pleev ib ce, tshuaj ntxuav tes thiab khoom tu tus kheej thiab lwm yam.
Cov txheej txheem rau kev npaj methyl hydrogen azelate feem ntau yog raws li hauv qab no:
1. Transesterification cov tshuaj tiv thaiv: cov tshuaj tiv thaiv transesterification yog nqa tawm nrog nonyl cawv thiab methyl formate nyob rau hauv lub xub ntiag ntawm acid catalyst kom tau methyl hydrogen azelate.
2. Direct esterification cov tshuaj tiv thaiv: esterification ntawm nonanol thiab formate nyob rau hauv qhov kev txiav txim ntawm acid catalyst los tsim methyl hydrogen azelate.
Nco ntsoov cov ntaub ntawv kev nyab xeeb hauv qab no thaum siv thiab tuav methyl hydrogen azelate:
1. methyl hydrogen azelate yog khaus thiab yuav tsum tau yaug tam sim ntawd thaum sib cuag nrog daim tawv nqaij thiab qhov muag.
2. Tsis txhob nqus cov pa ntawm methyl hydrogen azelate thiab siv rau hauv qhov chaw muaj cua zoo.
3. methyl hydrogen azelate muaj cov tshuaj toxicity tsawg, tab sis ntev ntev thiab loj-loj raug tej zaum yuav muaj kev cuam tshuam rau kev noj qab haus huv, thiab yuav tsum tsis txhob raug ntau dhau.
4. Thaum khaws cia thiab thauj methyl hydrogen azelate, khaws cia kom deb ntawm hluav taws kub thiab kub kom tsis txhob muaj kev phom sij ntawm kev sib tsoo thiab tawg.
Thov nco ntsoov tias ua ntej siv methyl hydrogen azelate lossis ib yam tshuaj, koj yuav tsum ua tib zoo nyeem thiab ua raws li cov txheej txheem kev nyab xeeb.
