Isku dhafka alkyl polyglycoside butyl ethers

Hantida inta badan loo baahan yahay ee alkyl polyglycosides ayaa kor u qaaday xumbo-samaynta.Si kastaba ha ahaatee, codsiyo badan, qaabkan ayaa dhab ahaantii loo arkaa mid aan faa'iido lahayn.Sidaa darteed, waxaa sidoo kale jira xiiso lagu horumarinayo derivatives alkyl polyglycoside kuwaas oo isku dara waxqabadka nadiifinta wanaagsan oo leh kaliya u janjeera xumbo.Iyadoo la tixgelinayo yoolkan, alkyl polyglycoside butyl ether ayaa la sameeyay.Waxaa lagu yaqaanaa suugaanta in alkyl glycosides lagu dabooli karo alkyl halides ama dimethyl sulfate ee xalalka aqueous alkaline.

Miisaanka warshadaha, falcelinta xalka aqueous waa khasaare sababtoo ah badeecooyinka biyo-la'aanta ah ee xoogga leh lama heli karo iyada oo aan la helin tallaabooyin shaqo oo dheeraad ah.Sidaa darteed, hannaan biyo la'aan ah ayaa la sameeyay, kaas oo lagu qeexay Jaantuska 6. Alkyl polyglycoside ayaa markii hore la galiyay reactor-ka iyadoo ay ka badan tahay chloride butyl waxaana lagu kululeeyaa 80 ℃.Dareen-celinta waxa lagu bilaabay in lagu daro potassium hydroxide sida kicinta.Marka falcelinta la dhammeeyo, isku darka falcelinta waa la dhexdhexaadin doonaa, soo da'da chloride potassium waa la sifeeyaa oo chloride butyl ee dheeraadka ah waa la nadiifiyaa.Alaabtu waxay ka kooban tahay alkyl polyglycosides kala duwan iyo alkyl polyglycoside butyl ethers.Marka loo eego falanqaynta GC, saamiga alkyl monoglycoside, alkyl mono-glycoside monobutyl ether iyo alkyl monoglycoside polybutyl ether waa 1: 3: 1.5.

Koorsada falcelinta etherification ee C₁₂alkyl polyglycoside waxa lagu muujiyay jaantuska 7. Maadada monoglycoside waxay hoos uga dhacday qiyaastii 70% ilaa in ka yar 20%.Isla mar ahaantaana, qiimaha monoether-ka ayaa kor u kacaya 50%.Inta badan ether-ka monobutyl ee jira, ayaa ka sii badanaya ether-yada polybutyl-ka ah ee laga samayn karo halkaas.Kaliya 24saac ka dib ayaa jira wax la taaban karo oo ah ether-yada polybutyl.Sida la filayo, waxa ku jira polyeter-yada waxay kordhisaa wakhtiga falcelinta ee sii kordheysa.Si kastaba ha ahaatee, qiimaha 20% lama dhaafo.Celceliska shahaadada etherification waa 1 ~ 3 butyl unugga alkyl glycoside.Saamaynta falcelinta C₁₂Alkyl glycoside ayaa ugu fiican.Xaaladda N = 8 ama 16 alkyl polyglycoside butyl ether, natiijadu way sii xumaatay.

Saddexdan tusaale waxaa iska cad in waxyaabaha ka soo jeeda alkyl glycosides ay diyaar yihiin.
