Solubility ntawm Methyl Cellulose Cov Khoom
Methyl cellulose yog ib qho dej-soluble polymer uas tau siv dav hauv ntau yam kev lag luam.Lub solubility ntawm methyl cellulose cov khoom nyob ntawm ntau yam, nrog rau kev hloov pauv, qhov hnyav molecular, kub, thiab pH.
Methyl cellulose cov khoom uas tsis muaj kev hloov pauv thiab qhov hnyav molecular tsawg yog soluble hauv dej ntau dua li cov khoom uas muaj kev hloov pauv ntau dua thiab hnyav dua molecular.Cov khoom lag luam methyl cellulose nrog qib siab dua ntawm kev hloov pauv thiab qhov hnyav dua molecular yuav xav tau qhov kub thiab txias dua los yog sib tov ntev dua kom yaj tag nrho hauv dej.
Cov pH ntawm cov tshuaj kuj tuaj yeem cuam tshuam rau solubility ntawm methyl cellulose.Methyl cellulose cov khoom yog feem ntau soluble nyob rau hauv nruab nrab los yog me ntsis acidic daws.Thaum pH ntau dua, solubility ntawm methyl cellulose txo qis.Qhov no yog vim ionization ntawm hydroxyl pawg ntawm cov pob txha cellulose, uas tuaj yeem txo qhov peev xwm ntawm cov dej molecules los cuam tshuam nrog cov saw hlau polymer.
Ntxiv rau cov dej, cov khoom methyl cellulose kuj tuaj yeem yaj hauv qee cov kuab tshuaj organic, xws li ethanol, methanol, thiab acetone.Txawm li cas los xij, solubility ntawm methyl cellulose nyob rau hauv cov kuab tshuaj no yog txwv thiab nyob ntawm seb qhov kev hloov pauv thiab qhov hnyav molecular ntawm cov khoom.
Hauv kev xaus, qhov solubility ntawm methyl cellulose cov khoom nyob ntawm ntau yam, nrog rau kev hloov pauv, qhov hnyav molecular, kub, thiab pH.Methyl cellulose cov khoom uas tsis muaj kev hloov pauv thiab qhov hnyav molecular yog ntau dua soluble hauv dej, thaum cov khoom uas muaj qib siab dua ntawm kev hloov pauv thiab qhov hnyav dua molecular yuav xav tau qhov kub thiab txias dua lossis ntev dua sib xyaw kom yaj tag.Methyl cellulose cov khoom yog feem ntau soluble nyob rau hauv nruab nrab los yog me ntsis acidic daws, thiab kuj yuav yaj nyob rau hauv ib co organic solvents, tab sis cov solubility nyob rau hauv cov kuab tshuaj no yog txwv.
