  • Publication number: 20130190463
    Abstract: A water soluble biodegradable polymer and a process for preparation thereof are disclosed. The polymer has characteristic NMR and FTIR peaks. The polymer is prepared by a process including preparing a mixture of phosphatides and triglycerides, reacting the mixture with an anhydride in an organic solvent in presence of a catalyst at an elevated temperature to obtain a reaction product, hydrolyzing the reaction product, thereafter separating the organic solvent from the reaction product, adding a second monomer with a catalyst to form a reaction mass, further curing the mass under stirring at reflux temperature, and finally cooling the cured mass and neutralizing it with caustic lye to obtain the polymer. The polymer is biodegradable and has high calcium sequestration and calcium salt inhibition properties suitable as an additive for detergents and water treatment applications.

  • Publication number: 20050020653
    Abstract: The invention relates to novel antifungal compounds and its pharmaceutically acceptable salts, having as part of its structure, imidazolyl or benzimidazolyl derivatives. The imidazolyl derivative may be substituted at 2 position from among the group consisting of aroyl, p-chloroaroyl, phenyl hydroxy methine or p-chloro phenyl hydroxy methine or with n-butyl at 2 position and chlorine at 4 and 5 position. In the alternative, when it is a benzimadazolyl derivative, with hydrogen at 6 position, the substituent at 2 position may be selected from among methyl, ethyl, isopropyl, 2-oxopropl-1-yl, n-propyl, methoxy methyl, propen-1-yl, phenyl, p-chlorophenyl, p-toluyl, benzyl, 4-pyridyl, p-methoxy phenyl, 3-pyridyl, o-methoxy phenyl, styryl, 2-cyano methyl, p-hydroxy phenyl, p-amino phenyl, p-toluyl sulfonyl methyl or p-(t-butyl) phenyl group and if hydrogen is at 2 position, the substituent at the 6 position is selected from among nitro, trifluoromethyl or methoxy group.
