Mishonga yeAlkyl Polyglycosides

Mazuvano, alkyl polyglycosides inowanikwa muhuwandu hwakakwana uye nemitengo yemakwikwi kuitira kuti kushandiswa kwavo sechigadzirwa chekugadzirwa kwevatsva vakasiyana-siyana vanogadzira kubva kune alkyl polyglycosides kuri kumutsa kufarira kukuru. Nekudaro, iyo surfactants zvimiro zvealkyl polyglycosides, semuenzaniso furo nekunyorova, zvinogona kugadziridzwa sezvinodiwa nekuchinja kwemakemikari.

Kubviswa kwealkyl glycosides ibasa rinoitwa zvakanyanya panguva ino.Kune marudzi akawanda ezvinyorwa zvealkyl glycoside nenzira ye nucleophilic substitution.Kuwedzera pakuita ne esters kana ethoxides, ionic alkyl polyglycoside derivatives, yakadai se sulfates uye phosphates, inogonawo kugadzirwa.

Kutanga kubva kualkyl polyglycosides ine alkyl cheni(R) ye8,10,12,14 uye 16 maatomu ecarbon.₈kuC₁₆）uye avhareji dhigirii yepolymerization (DP) ye1.1 kusvika 1.5, matatu akatevedzana ealkyl polyglycoside derivatives akagadzirwa. Kuti uongorore shanduko yezvivakwa zve surfactant hydrophilic kana hydrophobic substituents yakaunzwa ichitungamira kune alkyl polyglycoside glycerol ethers. (Mufananidzo 1)

Tichifunga nezvemapoka avo akawanda emahydroxyl, alkyl polyglycosides ari over-functionalized molecules.by far the most alkyl polyglycoside derivatizations anoitwa nekemikari shanduko yeyemahara primary hydroxyl group paC.⁶ atomu. Kunyange zvazvo mapoka ekutanga e-hydroxyl anonyanya kushandiswa kupfuura mapoka echipiri e-hydroxyl, musiyano uyu hauna kukwana mumatambudziko akawanda kuti uwane sarudzo yakasarudzwa pasina mapoka ekudzivirira.Nekudaro, kubuda kwealkyl polyglycoside kunogona kutarisirwa nguva dzose kubudisa musanganiswa wechigadzirwa icho chimiro chinosanganisira kuedza kukuru kwekuongorora. Musanganiswa wegasi chromatography uye misa spectrometry yakaratidzwa seyo yakasarudzika nzira yekuongorora. Mukugadzirwa kwealkyl polyglycoside derivatives, zvakaratidza kushanda kushandisa alkyl polyglycoside ine yakaderera DP kukosha kwe1.1, mune zvinotevera zvinonzi alkyl monoglycosides. Izvi zvinotungamira kune kushomeka kwechigadzirwa musanganiswa uye semhedzisiro kune kushoma ongororo.
