Njikọ nke alkyl polyglycoside butyl ethers

Ngwongwo a na-achọkarị nke alkyl polyglycosides na-eme ka ụfụfụ dịkwuo elu. Agbanyeghị, n'ọtụtụ ngwa, a na-ewere njirimara a dị ka ihe na-adịghị mma. Ya mere, enwekwara mmasị n'ịmepụta ihe ndị na-emepụta alkyl polyglycoside nke na-ejikọta ọrụ nhicha dị mma na-enwe nanị ntakịrị ọchịchọ nke ụfụfụ. N'ịtụle ebumnuche a, a na-emepụta alkyl polyglycoside butyl ether. A maara na akwụkwọ akụkọ na alkyl glycosides nwere ike kpuchie ya na alkyl halides ma ọ bụ dimethyl sulfate na ngwọta mmiri alkaline.

N'ọtụtụ ụlọ ọrụ mmepụta ihe, mmeghachi omume na ngwọta aqueous bụ ihe na-adịghị mma n'ihi na enweghị ike ịnweta ngwaahịa na-enweghị mmiri na-enweghị ihe mgbakwunye na-arụ ọrụ. Ya mere, e mepụtara usoro na-enweghị mmiri, nke e depụtara na foto 6. A na-ebute alkyl polyglycoside na mbụ n'ime reactor na oke nke butyl chloride ma kpoo ọkụ ruo 80 ℃. A na-amalite mmeghachi omume site na mgbakwunye nke potassium hydroxide dị ka ihe na-akpata. Mgbe emechara mmeghachi omume ahụ, ngwakọta mmeghachi omume na-apụ apụ, a na-ekpochapụ potassium chloride precipitate ma kpochapụ butyl chloride ngafe. Ngwaahịa a bụ nke dị iche iche alkyl polyglycosides na alkyl polyglycoside butyl ethers. Dabere na nyocha GC, oke nke alkyl monoglycoside, alkyl mono-glycoside monobutyl ether na alkyl monoglycoside polybutyl ether bụ 1: 3: 1.5.

Usoro mmeghachi omume maka etherification nke C₁₂A na-egosi alkyl polyglycoside na eserese 7. Ọdịnaya monoglycoside na-agbada site na gburugburu 70% ruo ihe na-erughị 20%. N'otu oge ahụ, uru maka monoether na-ebili na 50%. Ka monobutyl ether dị ugbu a, otú ahụ ka e nwere ike isi na ya mepụta ọtụtụ ethers polybutyl. Naanị mgbe awa 24 gachara, a na-enwe mmetụta ọ bụla dị mkpa nke ethers polybutyl. Dị ka a tụrụ anya, ọdịnaya nke polyethers na-abawanye na oge mmeghachi omume na-abawanye. Agbanyeghị, uru nke 20% agafebeghị. Nkezi ogo etherification bụ 1 ~ 3 butyl kwa otu alkyl glycoside. Mmetụta mmeghachi omume nke C₁₂Alkyl glycoside bụ ihe kacha mma. N'ihe gbasara N = 8 ma ọ bụ 16 alkyl polyglycoside butyl ether, nsonaazụ ya dara.

Site na ihe atụ atọ a, o doro anya na ihe ndị sitere na alkyl glycosides dị ngwa ngwa. Ojiji pụrụ iche a na-atụ anya na-adaberekwa na njirimara elu-arụ ọrụ nke ihe ndị a.
