摘要:考察了三种非离子型二乙醇酰胺表面活性剂的纯净状态和溶致液晶相行为,它们含有c18碳氢链,分别带有一个,两个或三个不饱和键.这使得可以探讨不饱和度对二乙醇酰胺表面活性剂相行为的影响.纯净的亚油酰基和亚麻酰基二乙醇酰胺在约−85 oc时发生从玻璃态液晶到液晶的相变,而纯净的油酰基二乙醇酰胺在约−60 oc时发生相变形成液晶材料,然后在−34 oc时再结晶.油酰基二乙醇酰胺随后在约5 oc时发生第三次相变,从晶态相转变为碟状液晶相.在没有水的情况下,从碟状液晶到各向同性液体的转变温度随着不饱和度的增加而降低.加入水会导致所有三种表面活性剂形成层状相(lα).层状相在水过量条件下至少在70 oc下稳定.为这三种不饱和c18表面活性剂反应生成的近似部分二元表面活性剂-水相图表明,每种表面活性剂的过量水点出现在约60%(重量比)表面活性剂.

摘要:A toner for electrostatic charge developing prepared by a production method including aggregating one or more kind of particles in a raw material dispersion including the particles to form aggregated particles, and coalescing the aggregated particles by heating. At least one kind of the particles is resin particles including an amorphous polyester resin synthesized by copolymerizing one or more polyvalent carboxylic acids and two or more polyhydric alcohols; at least one of the polyvalent carboxylic acids is polyvalent carboxylic acid having a sulfonic acid group; two of the polyhydric alcohols are an ethylene oxide adduct of bisphenol A and a propylene oxide adduct of bisphenol A; and the following equation is satisfied:n n10/90≦ BPA ( EO )/ BPA ( PO )≦90/10.n n In the equation, BPA(EO) represents a total mole amount of the ethylene oxide adduct of bisphenol A used in synthesis of the amorphous polyester resin, and BPA(PO) represents a total mole amount of the propylene oxide adduct of bisphenol A used in synthesis of the amorphous polyester resin.

标 题 :Hydroaminomethylation of olefins
发明人：BRIGGS JOHN R; WHITEKER GREGORY T; KLOSIN JERZY
权利人:DOW GLOBAL TECHNOLOGIES INC
摘要:The present invention relates to a method comprising the step of contacting under hydroaminomethylation conditions, an olefin, an amine, a rhodium-phosphorous ligand, and synthesis gas (syngas). In particular, it has been discovered that, under some circumstances, a neutral rhodium-monodentate phosphite ligand is prescribed. The invention provides a simple way of making, in high yields and regiospecificity, a variety of products, including pharmacologically active products such as ibutilide, terfenadine, and fexofenadine, and derivatives thereof.

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.
