Pane nzira dzinoverengeka dzekugadzira alkyl polyglycosides kana alkyl polyglucosides musanganiswa.Nzira dzakasiyana-siyana dzekugadzira dzinobva kune stereotactic synthetic nzira uchishandisa mapoka ekudzivirira (kuita kuti makomisheni asarudze zvakanyanya) kune isingasarudze nzira dzekugadzira (kusanganisa isomers nemaoligomers).
Chero nzira yekugadzira yakakodzera kushandiswa pachiyero cheindasitiri inofanirwa kusangana nemaitiro akati wandei.Zvinonyanya kukosha kugadzira zvigadzirwa zvine zvivakwa zvakakodzera uye maitiro ehupfumi.Pane zvimwe zvinhu, sekuderedza mhedzisiro kana tsvina uye kuburitsa.Iyo tekinoroji inoshandiswa inofanirwa kuchinjika kuitira kuti mashandiro echigadzirwa uye hunhu hwemhando hugone kuchinjika kune zvinodiwa pamusika.
Mukugadzirwa kwemaindasitiri kwealkyl polyglycosides, maitiro akavakirwa paFischer synthesis akabudirira.Kubudirira kwavo kwakatanga makore makumi maviri apfuura uye kwakawedzera mumakore gumi apfuura.Kubudirira panguva iyi kwakabvumira nzira yekubatanidza kuti iwedzere kushanda uye pakupedzisira inoyevedza kumaindasitiri ekushandisa.Optimizations inoshanda, kunyanya mukushandiswa kwezvinwiwa zvenguva refu senge dodecanol/tetradecanol
(C12-14 -OH), vakavandudza zvakanyanya kunaka kwechigadzirwa uye maitiro ehupfumi.Iyo yemazuva ano yekugadzira chirimwa chigadziko paFischer Synthesis ndiyo inofananidzira yakaderera tsvina, zero emission tekinoroji.Imwe mukana weFischer synthesis ndeyekuti avhareji dhigirii yepolymerization yezvigadzirwa inogona kudzorwa pamusoro pehupamhi hwekurongeka.Naizvozvo, zvivakwa zvine hukama, senge hydrophilicity / mvura-solubility, inogona kugadziridzwa kuti isangane nezvinodiwa.Uye zvakare, iyo yakaomeswa base base haichabatiki neanhydrous glucose.
1. Zvigadzirwa zvekugadzirwa kwealkyl polyglycosides
1.1 Fatty Doro
Fatty alcohols inogona kuwanikwa kubva petrochemical feedstocks (synthetic fatty alcohols) kana kubva kune zvakasikwa, zvinogonekazve zviwanikwa zvakaita semafuta neoiri (yakasikwa mafuta doro).Mafuta edoro musanganiswa anoshandiswa mukugadzirwa kwealkyl glycosides kumisikidza iyo hydrophobic chikamu chemorekuru.Zvinwiwa zvechisikigo zvemafuta zvakawanikwa ne transesteration uye kupatsanurwa kwemafuta uye girizi (triglyceride) kuti iite inowirirana fatty acid methyl ester, uye hydrogenated.Zvichienderana nehurefu hwemafuta anodhaka alkyl chain anodiwa, izvo zvinonyanya kushandiswa mafuta nemafuta: kokonati kana palm kernel mafuta eC12-14 series, uye tallow, palm kana rapeseed mafuta eC16-18 mafuta anodhaka.
1.2 Carbohydrate sosi
Iyo hydrophilic chikamu chealkyl polyglycoside molecule inotorwa kubva kune carbohydrate.
Macromolecular carbohydrates uye monomer carbohydrates anobva pane starch ye
chibage, gorosi kana mbatatisi uye inogona kushandiswa seyakagadzirwa kugadzirwa kwealkyl glycosides.Semuenzaniso, mapolymer carbohydrates anosanganisira kuderera kwemazinga e starch kana glucose syrup, nepo monomer carbohydrates inogona kuva chero rudzi rweglucose, yakadai seanhydrous glucose, monohydrate glucose, kana yakanyanya kuderedzwa glucose sirasi.
Raw material sarudzo haingopesvedzeri chete mutengo wemidziyo, asiwo mutengo wekugadzira.
Kazhinji, mari yemidziyo inokwira muodha yestarch/glucose syrup/glucose monohydrate/yemvura-isina glucose nepo zvinodiwa zvemidziyo yekudyara nekudaro mitengo yekugadzira inodzikira muhurongwa humwe chete.(Mufananidzo 1)
