摘要:制备酯的最常用方法是通常由酸催化的羧酸的酯化,通过共沸去除水使平衡转移到产物.某些酸如h,So或对甲苯磺酸具有强腐蚀性,必须使用大量有机溶剂和较长的反应时间.这种方法也会导致环境问题.虽然固体酸催化剂是一种改进,但它们的使用也需要几个小时才能完成反应.' 微波在有机合成中的应用是由 Gedye 和 Majetich 及其同事在 1986 年的开创性工作引发的.最近的报告表明,与传统加热相比,有机反应可以在微波炉中安全地进行,其反应速度显着提高,反应时间显着减少.在这些研究中,无溶剂条件受到越来越多的关注,因为它们具有避免使用溶剂和对环境更友好的优势.~ 无溶剂条件下微波辐射对酯化速率的影响也进行了研究.5 使用蒙脱石催化剂在羧酸或羧酸根离子与卤代烃的酯化中获得了非常好的结果.但在工业上普遍使用的羧酸与醇的酯化反应中,使用无机固体载体如硅胶(sio2),氧化铝(a120J,经证明,无溶剂反应下

摘要:A composition is provided, wherein the composition comprises a water-swellable, water insoluble polymer, a blend of a hydrophilic polymer and a complementary oligomer capable of hydrogen bonding to the hydrophilic polymer, and a whitening agent, preferably a peroxide. The composition finds utility as a tooth whitening composition and is applied to the teeth in need of whitening, and then removed when the degree of whitening has been achieved. In certain embodiments, the composition is translucent. Methods for preparing and using the compositions are also disclosed.

标题:Polyurethane synthesis from functional group terminated polymers containing sulfonate groups
发明人：CHANG WALLY L
权利人:WITCO CORP
摘要:Disclosed is a process for producing water-dispersible polyurethanes by forming an isocyanate-di-substituted prepolymer and reacting it with a chain extender. The prepolymer can be formed by reacting a diisocyanate with an ethylenically unsaturated precursor which is preferably formed by condensation polymerization of reactants including ethylenically unsaturated reactants and then sulfonating the ethylenic unsaturation of said polymeric precursor by reacting it with a sulfonating agent such as bisulfite, metabisulfite, or a mixture thereof.

标 题 :Asymmetric Cyclic Diester Compounds
发明人：BRADSHAW JOHN D; SCHAEFER GEORGE F; BALDWIN LARRY J; RALEIGH JR RONALD J; HOLLO BRENDA
权利人:FERRO CORP
摘要:Compounds useful as plasticizers and the synthesis thereof are disclosed. In general, the invention includes mixed alkyl/aryl asymmetric cyclic diesters where the aryl and alkyl ester moieties are attached to a cyclic structure at vicinal carbons. The invention also includes synthetic processes of making such compounds. Blends of these asymmetric cyclic diesters with other plasticizers are demonstrated to be of use in plasticizing polymers.
