Alkyl Polyglycosides derivatives

I kēia mau lā, loaʻa nā alkyl polyglycosides i nā nui kūpono a me nā kumukūʻai hoʻokūkū i mea e hoʻoulu nui ai kā lākou hoʻohana ʻana ma ke ʻano he mea maka no ka hoʻomohala ʻana i nā surfactants kūikawā hou e pili ana i nā alkyl polyglycosides. No laila, hiki ke hoʻololi ʻia nā waiwai surfactant o nā alkyl polyglycosides, no ka laʻana, ka huʻa a me ka pulu, e like me ke koi ʻia e ka hoʻololi kemika.

ʻO ka loaʻa ʻana o nā alkyl glycosides kahi hana i hana nui ʻia i kēia manawa. He nui nā ʻano o ka alkyl glycoside derivatives ma o ka nucleophilic substitution. .

E hoʻomaka ana mai nā polyglycosides alkyl me nā kaulahao alkyl(R) o 8,10,12,14 a me 16 mau kalapona kalapona(C8iā C16) a me ka awelika degere o ka polymerization (DP) o 1.1 a i 1.5, ua hoomakaukauia ekolu moo o na alkyl polyglycoside derivatives. I mea e noiʻi ai i ka hoʻololi ʻana i nā waiwai surfactant hydrophilic a i ʻole hydrophobic substituents ua hoʻokomo ʻia e alakaʻi ana i nā alkyl polyglycoside glycerol ethers. (Kiʻi 1)

I ka nānā ʻana i kā lākou mau pūʻulu hydroxyl he nui, ʻoi aku ka nui o nā molekiko alkyl polyglycosides.6 ʻātoma. ʻOiai ʻoi aku ka paʻakikī o nā pūʻulu hydroxyl mua ma mua o nā pūʻulu hydroxyl lua, ʻaʻole lawa kēia ʻokoʻa i ka hapanui o nā hihia e hoʻokō i kahi hopena koho me ka ʻole o nā pūʻulu pale. nui ka hooikaika ana. ʻO ka hui pū ʻana o ka chromatography kinoea a me ka spectrometry nuipa i hōʻike ʻia ʻo ia ke ʻano loiloi makemake. I ka hoʻohui ʻana o ka alkyl polyglycoside derivatives, ua hōʻike ʻia ka maikaʻi o ka hoʻohana ʻana i kahi alkyl polyglycoside me kahi waiwai DP haʻahaʻa o 1.1, ma ka mea i kapa ʻia ʻo alkyl monoglycosides. Ke alakaʻi nei kēia i nā hui ʻana o nā huahana liʻiliʻi a ma muli o ka hoʻopili liʻiliʻi paʻakikī.
