标 题:Polyester synthesis
发明人:WOSNICK JORDAN H
权利人:XEROX CORP
摘要:The present disclosure provides for enzymatic polymerization to produce polyester resins suitable for use in manufacturing toners. In embodiments, crystalline copolymers, which are polyesters, may be synthesized from lactones, cyclic anhydrides, cyclic carbonates, and combinations thereof. These crystalline copolymers, in turn, may be utilized in the synthesis of toner particles.

标 题:Methods for the production of polymer carrier materials based on carbon hydrate-bis(meth)acryl-amides
发明人:VERDIANZ THOMAS; GRUBER HEINRICH; KNAUS SIMONE; POSCHALKO ALEXANDER
权利人:TECH UNI
摘要:The invention relates to methods for the production of polymer carrier materials for solid phase synthesis, particularly for peptide synthesis. (Meth)acrylamide derivatives based on carbon hydrates, which can also contain other protective groups, are polymerized by means of suspension polymerization in an aqueous phase, optionally with the addition of pore-forming additives, and subsequently the protective groups are fully or partially cleaved. It is thus possible to obtain polymer carriers whose morphology (particle size, porosity), degree of cross-linking and swelling capability in aqueous and organic media can be adjusted in a targeted manner and whose reactive groups offer multiple opportunities for the immobilization of anchor groups and protective groups. The hydroxyl groups of the polymer carrier can be activated according to usual methods of solid phase synthesis.

标 题:Use of recycled byproducts to create hydrogen for use in conversion of olefins to jet fuel
发明人:BENNETT III ERICK J; JERORO ESEOGHENE
权利人:BENNETT III ERICK J; JERORO ESEOGHENE
摘要:A process for providing hydrogen in a process to produce jet fuel from methanol comprising producing a supply of hydrogen from a hydrogen production unit to be sent to one or more vessels within said process and wherein additional supplies of hydrogen are recovered from a recycle stream or recycle streams from one or more reactors or vessels and sent to supplement the first supply of hydrogen. The additional supplies of hydrogen are recovered from a hydrogenation reactor downstream of an oligomerization reactor, a methanol synthesis reactor or a hydrogenation reactor downstream from a DME water column and sent to the methanol synthesis reactor, hydrogenation reactor or acetylene converter.
