    Abstract: Provided is a sevoflurane anesthetic product which can remain substantially undegraded after long periods of storage, as well as a method for preparing the product. The product comprises sevoflurane in a glass container having a water content of less than 130 ppm. The method comprises drying sevoflurane having a water content of greater than 130 ppm to a water content les than 130 ppm. A preferred method of drying comprises contacting a sevoflurane composition having a water content of greater than 130 ppm with alumina-containing molecular sieves such that the water content is reduced to less than 130 ppm.

    Abstract: A composition for removing urethane products from a wide variety of substrates without the need for scraping, scrubbing, sanding, sandblasting and the like is provided. The composition is formed by combining water, a polar organic solvent, a mixture of organic esters, a hydrocarbon, and a polyether. The composition may optionally be formed by combining the components recited above along with an anionic surfactant. The composition may optionally be formed by combining the components recited above along with a thickener.

    Abstract: A method for preparing p-(2-hydroxyalkyloxy)styrene monomers and oligomers is described. The method comprises a base-catalyzed reaction of a styrene ester, a suitable alcohol and an alkylene oxide in a single vessel reaction. In this method, the reactive p-hydroxystyrene is generated in situ via the base-catalyzed transesterification reaction between the styrene ester and the alcohol in the presence of the base catalyst. The p-hydroxystyrene formed reacts with the alkylene oxide to form the p-(2-hydroxyalkyloxy)styrene monomer or oligomer.

    Abstract: The present invention is a novel process, with or without solvent, for manufacture of compounds of formula (a), wherein P is selected from phenyl and naphthyl; wherein R1 and R2 and R3 are each independently selected from hydrogen, alykl, alkoxy, aryl, aralkyl, aralkoxy, halogen, alkoxyalkoxy, and aralkoxyalkoxy; wherein R5 is selected from substituted or unsubstituted phenyl, and substituted or unsubstituted naphthyl, the substituents being each independently selected from alkyl (C1-C8), alkoxy (C1-C8), aroxy, aralkoxy (C1-C8) and halogen. The process comprises reacting substituted phenols or naphthols of the formula (b) with ethylene carbonate in the presence of a first catalyst selected from metal halide, quaternary ammonium halide and quarternary phosphonium halide thereby forming an intermediate of the formula (c), then reacting the intermediate with a first compound selected from alkyl or aralkylhalide, alkyl or aralkyl sulfate, and alkyl or aralkyl sulfonate together with a metal hydroxide in the presence of a second catalyst, the second catalyst selected from quaternary ammonium salt or quaternary phosphonium salt.
