Motsoako oa alkyl polyglycoside butyl ethers

Thepa e hlokoang khafetsa ea alkyl polyglycosides ke ho foamability e matlafalitsoeng. Leha ho le joalo, lits'ebetsong tse ngata, tšobotsi ena e hlile e nkuoa e le monyebe. Ka hona, ho boetse ho na le thahasello ea ho hlahisa lihlahisoa tsa alkyl polyglycoside tse kopanyang ts'ebetso e ntle ea ho hloekisa le tšekamelo e fokolang feela ea ho foam. Ha ho nahanoa ka sepheo sena, alkyl polyglycoside butyl ether e ile ea etsoa. Hoa tsebahala libukeng hore alkyl glycosides e ka koaheloa ka alkyl halides kapa dimethyl sulfate ka tharollo ea metsi a alkaline.

Boemong ba indasteri, karabelo ea tharollo ea metsi ke mofokoli hobane lihlahisoa tse se nang metsi tse ngata li ke ke tsa fumanoa ntle le mehato e meng ea ho sebetsa. Ka hona, ho ile ha etsoa mokhoa o se nang metsi, o hlalositsoeng ho Setšoantšo sa 6. Alkyl polyglycoside e qala ho kenngoa ka har'a mochine o nang le butyl chloride e feteletseng 'me e futhumetse ho 80 ℃. Karabelo e qalisoa ka ho eketsoa ha potassium hydroxide e le sesosa. Ha karabelo e phetheloa, motsoako oa karabelo ha o fokotsehe, potassium chloride precipitate e sefshoa ebe butyl chloride e feteletseng e tlosoa. Sehlahisoa sena se entsoe ka mefuta e fapaneng ea alkyl polyglycosides le alkyl polyglycoside butyl ethers. Ho latela tlhahlobo ea GC, karo-karolelano ea alkyl monoglycoside, alkyl mono-glycoside monobutyl ether le alkyl monoglycoside polybutyl ether ke 1:3:1.5.

Mokhoa oa karabelo bakeng sa etherification ea C₁₂alkyl polyglycoside e bontšoa ho Setšoantšo sa 7. Likahare tsa monoglycoside li fokotseha ho tloha ho pota 70% ho ea ho tlase ho 20%. Ka nako e ts'oanang, boleng ba monoether bo nyolohela ho 50%. Ha e ntse e le monobutyl ether e eketsehileng, li-ether tse ngata tsa polybutyl li ka thehoa ho eona. Ke feela ka mor'a lihora tse 24 ho na le sebopeho sa bohlokoa sa polybutyl ethers. Joalo ka ha ho lebelletsoe, litaba tsa polyethers li eketseha ka nako e ntseng e eketseha ea karabelo. Leha ho le joalo, boleng ba 20% ha bo fete. Karolelano ea tekanyo ea etherification ke 1 ~ 3 butyl ka yuniti ea alkyl glycoside. Phello ea karabelo ea C₁₂alkyl glycoside e ne e le eona e ntle ka ho fetisisa. Tabeng ea N =8 kapa 16 alkyl polyglycoside butyl ether, liphetho li ile tsa senyeha.

Ho tsoa mehlala ena e meraro ho hlakile hore li-derivatives tsa alkyl glycosides li fumaneha habonolo.Litšebeliso tse khethehileng tse lebelletsoeng li boetse li itšetlehile ka thepa ea ts'ebetso ea holim'a lihlahisoa tsena.
