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 ka 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 puta he hanganga nui o te polybutyl ethers. Ka rite ki te tumanako, ka piki ake te ihirangi o te 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.
