Sodium carboxymethyl cellulose solubility hauv dej

Taw qhia

Carboxymethyl cellulose (CMC) yog ib hom cellulose derivative uas tau siv dav hauv ntau yam lag luam, suav nrog zaub mov, tshuaj, ntawv, thiab textiles.Nws yog cov dej-soluble polymer uas yog tsim los ntawm reacting cellulose nrog sodium monochloroacetate los yog sodium dichloroacetate nyob rau hauv lub xub ntiag ntawm alkali.CMC yog cov hmoov dawb, tsis muaj ntxhiab, tsis qab, uas yog siv los ua tus neeg sawv cev thickening, stabilizer, emulsifier, thiab tshem tawm tus neeg sawv cev hauv ntau yam khoom.Nws kuj yog siv los ua cov ntawv khi hauv cov ntsiav tshuaj thiab cov tshuaj ntsiav, thiab ua cov roj nplua nyeem hauv kev tsim cov ntsiav tshuaj.

Kev solubility ntawm CMC hauv dej nyob ntawm ntau yam, suav nrog qib kev hloov pauv (DS), qhov hnyav molecular, thiab pH.Lub degree ntawm kev hloov pauv yog tus naj npawb ntawm carboxymethyl pawg ib chav tsev anhydroglucose (AGU) hauv cov saw hlau polymer, thiab feem ntau yog qhia raws li feem pua.Qhov siab dua DS, ntau hydrophilic CMC thiab ntau soluble nws nyob hauv dej.Qhov hnyav molecular ntawm CMC kuj cuam tshuam rau nws cov solubility hauv dej;siab dua molecular hnyav yuav ntau soluble.Thaum kawg, pH ntawm cov tshuaj kuj tuaj yeem cuam tshuam cov solubility ntawm CMC;siab pH qhov tseem ceeb yuav ua rau kom cov solubility ntawm CMC.

Kev solubility ntawm CMC hauv dej kuj cuam tshuam los ntawm kev muaj lwm yam tshuaj hauv cov tshuaj.Piv txwv li, muaj cov electrolytes xws li sodium chloride tuaj yeem txo qhov solubility ntawm CMC hauv dej.Ib yam li ntawd, muaj cov kuab tshuaj organic xws li ethanol tuaj yeem txo qhov solubility ntawm CMC hauv dej.

Kev solubility ntawm CMC hauv dej tuaj yeem txiav txim siab los ntawm kev ntsuas qhov concentration ntawm CMC hauv kev daws teeb meem siv lub spectrophotometer.Qhov concentration ntawm CMC hauv cov tshuaj tuaj yeem txiav txim siab los ntawm kev ntsuas qhov nqus ntawm cov tshuaj ntawm lub wavelength ntawm 260 nm.Lub absorbance yog proportional rau qhov concentration ntawm CMC nyob rau hauv cov tshuaj.

Feem ntau, CMC yog soluble hauv dej heev.Kev solubility ntawm CMC hauv dej nce nrog nce qib ntawm kev hloov pauv, qhov hnyav molecular, thiab pH.Kev solubility ntawm CMC hauv dej kuj cuam tshuam los ntawm kev muaj lwm yam tshuaj hauv cov tshuaj.
