Bio - based PBS copolyesters derived from a bicyclic D - glucitol
2,4:3,5-di-O-methylene-D-glucitol (Glux-diol) was used for the synthesis of poly(butylene 10 succinate) (PBS) copolyesters by melt polycondensation. Glux-diol possess a rigid bicyclic 11 asymmetric structure made of two fused 1,3-dioxane rings and two hydroxyl functions at the end 12 positions. Copolyesters were prepared over the whole range of compositions with molecular 13 weights varying fro...
متن کاملA Formal Total Synthesis of Deoxynojirimycin from D-Glucitol
Descrevemos a síntese formal da desoxinojirimicina usando D-glucitol como material de partida economicamente atraente. Através de uma seqüência de reações de proteção e desproteção seletivas e reações de substituição nucleofílica obtivemos diversos intermediários isopropilidênicos. A formação de um epóxido intermediário e sua subseqüente abertura, através de uma reação nucleofílica intramolecul...
متن کاملPolarized Emission of Wholly Aromatic Bio-Based Copolyesters of a Liquid Crystalline Nature
A novel thermotropic liquid crystalline polymers poly{3-benzylidene amino-4-hydroxybenzoic acid (3,4-BAHBA)-co-trans-4-hydroxycinnamic acid (4HCA: trans-coumaric acid)} (Poly(3,4-BAHBA-co-4HCA)), was synthesized by the thermal polycondensation of 4HCA and 3,4-BAHBA, which was synthesized by a reaction of 3-amino-4-hydroxybenzoic acid (3,4-AHBA) with benzaldehyde. When the 4HCA compositions of P...
متن کاملA Novel Bio-based Sulfonic Zwitterionic Surfactant Derived from Transgenic Soybean Oil and its Performance in Surface and Interfacial Activities
Bio-based surfactants have attracted increasing attention due to their renewable resources and excellent surface properties. In this study, a novel bio-based sulfonic zwitterionic surfactant (BSZS) derived from transgenic soybean oil was prepared using a simple reaction route with two steps of the amidation and quaterisation. The bio-based sulfonic zwitterionic surfactant showed a critical mice...
متن کاملCopolyesters made from 1,4-butanediol, sebacic acid, and D-glucose by melt and enzymatic polycondensation.
Biotechnologically accessible 1,4-butanediol and vegetal oil-based diethyl sebacate were copolymerized with bicyclic acetalized D-glucose derivatives (Glux) by polycondensation both in the melt at high temperature and in solution at mild temperature mediated by polymer-supported Candida antarctica lipase B (CALB). Two series of random copolyesters (PB(x)Glux(y)Seb and PBSeb(x)Glux(y)) were prep...
