Te whakahiato o nga alkyl polyglycoside butyl ethers

Ko tetahi taonga e hiahiatia ana mo te polyglycosides alkyl ko te whakakaha ake i te hukahuka.Heoi, i roto i te maha o nga tono, ka kiia tenei ahuatanga he kino.Na reira, he hiahia ano ki te whakawhanake i nga pärönaki polyglycoside alkyl e whakakotahi ana i nga mahi horoi pai me te ahua paku noa ki te pahuka.Ma te whakaaro ki tenei whainga, i whakahiatotia te alkyl polyglycoside butyl ether.E mohiotia ana i roto i nga tuhinga ka taea te kapi i te alkyl glycosides ki te alkyl halides, dimethyl sulfate ranei i roto i nga wairewa wai kawakore.

I runga i te tauine ahumahi, he kino te tauhohenga i roto i te wairewa wai na te mea kaore e taea te whiwhi hua-kore-wai-kore ki te kore he mahi taapiri.Na reira, i hangaia he tukanga wai-kore, e whakaatuhia ana i te Whakaahua 6. Ko te polyglycoside alkyl i te tuatahi ka whakauruhia ki roto i te reactor me te nui o te butyl chloride me te wera ki te 80 ℃.Ka timata te tauhohenga ma te taapiri i te konupora waiwai hei whakakorikori.I te otinga o te tauhohenga, ka whakakorehia te ranunga tauhohenga, ka tātarihia te konutai konupora chloride ka whakakorehia te nui o te butyl chloride.Ko te hua he maha nga momo alkyl polyglycosides me nga alkyl polyglycoside butyl ethers.E ai ki te tātaritanga GC, ko te ōwehenga o te alkyl monoglycoside, alkyl mono-glycoside monobutyl ether me te alkyl monoglycoside polybutyl ether he 1:3:1.5.

Ko te mahinga o te tauhohenga mo te whakaetere o te C12Ko te polyglycoside alkyl e whakaatuhia ana i te Whakaahua 7. Ka heke te ihirangi monoglycoside mai i te 70% ki te iti iho i te 20%.I te wa ano, ka piki te uara mo te monoether ki te 50%.Ko te nui ake o te monobutyl ether, ka nui ake nga polybutyl ethers ka taea te hanga mai i reira.I muri noa iho i nga haora 24 ka kitea he hanganga nui o te polybutyl ethers.Ka rite ki te tumanako, ka piki te ihirangi o nga polyether me te piki haere o te wa tauhohenga.Heoi, karekau e neke ake te uara o te 20%.Ko te tohu etherification toharite ko 1 ~ 3 butyl ia wae alkyl glycoside.Ko te hua o te tauhohenga o C12Ko te alkyl glycoside te mea pai.I te take o N =8, 16 alkyl polyglycoside butyl ether ranei, kua kino nga hua.

Mai i enei tauira e toru ka maarama kei te waatea noa nga hua o te alkyl glycosides.
