摘要:3-(三苯基膦亚氯)丙烯酸和 2,3-二氯丙酸与三苯基膦反应反应生成1,2-双(三苯基膦亚氯)乙烷.在类似条件下,2,3-二溴丙酸发生脱溴反应,然后加入三苯基膦,经水处理后反应生成3-(三苯基膦溴化)丙酸.2,3-二卤代丙腈发生类似反应,反应生成3-(三苯基膦卤代)丙腈.2,3-二溴丙酰胺与三苯基膦的反应表明,E-(三苯基膦溴)丙烯酸能够与三苯基膦发生反应,这与之前的报道不同.吡啶与 2,3-二氢丙酸形成乙烯基吡啶鎓卤化物,而与脂肪族胺反应则产生脱氢卤化产物.

权利人:NEWSOUTH INNOVATIONS PTY LTD
摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

摘要:An improved process for synthesizing acrylic polymers, which is highly controllable to achieve high molecular weight, high conversion rate, and low polydispersity involves continuously introducing initiator(s), acrylic monomer(s), and optionally other monomers capable of polymerizing with the acrylic monomer(s), into a microchannel of a microreactor having an integral micromixer and an integral heat exchanger.

标 题:Process for the preparation of fluorescent brightener formulations which are stable on storage
发明人：HORLACHER PAUL; PFENNINGER HEINZ
权利人:CIBA GEIGY CORP
摘要:A process is described for the preparation of concentrated liquid formulations, stable on storage, of anionic fluorescent brighteners, which process consists in passing a crude (for example obtained from synthesis) aqueous solution or dispersion of a fluorescent brightener containing sulfo groups, in particular a stilbene fluorescent brightener belonging to the group comprising bistriazinylaminostilbenedisulfonic acids, bis-styrylbiphenyls, bis-styrylbenzenes and bis-triazolylstilbenedisulfonic acids, is passed through a semipermeable membrane which contains ionic groups and has a pore diameter of 1-500 ANGSTROM in order to remove salts and by-products from the synthesis having molecular weights below 500 and in order to remove part of the water. The resulting concentrated preparation can, if desired, be concentrated further and/or treated with formulation assistants and, if desired, further additives.

发明人：MOSBACH KLAUS; CORMACK PETER A G; RAMSTROEM OLOF; HAUPT KARSTEN
摘要:Compounds which possess a complementary structure to a desired molecule, such as a biomolecule, in particular polymeric or oligomeric compounds, which are useful as in vivo or in vitro diagnostic and therapeutic agents are provided. Also, various methods for producing such compounds are provided. These polymeric or oligomeric compounds are useful in particular as antimicrobial agents, receptor, hormone or enzyme agonists and antagonists.

标 题:Process for the preparation of solid composition of water-soluble dyes
发明人：BRUTTEL BEAT; PFENNINGER HEINZ
权利人:CIBA GEIGY CORP
摘要:A process for producing solid dye compositions, which process comprises passing an aqueous solution or suspension of at least one water-soluble crude dye, to effect separation of synthesis by-products having a molecular weight of below 500 and partial separation of water, through a semipermeable membrane, subsequently drying the resulting aqueous preparation which has become more highly concentrated, and optionally adding further additives before and/or after passage of the aqueous solution or suspension through the semipermeable membrane, these additives being added beforehand only when they do not become separated by the membrane. There are obtained by this process low-dust to dust-free compositions which are distinguished by high mechanical strength, high bulk density, free-flowing characteristics and good dissolving behavior. Employing these compositions it is possible to prepare low-foam to foam-free aqueous dye liquors having very good solution stability, even in the presence of electrolytes.
