  • Patent number: 11267915
    Abstract: The present disclosure provides an effective and efficient process for the preparation of a dry chlorinated polyvinyl chloride (CPVC), comprising introducing chlorine gas into slurry of polyvinyl chloride in water to obtain a reaction mixture; irradiating the reaction mixture to obtain a product mixture comprising CPVC and water solution including unreacted chlorine gas and hydrogen chloride; filtering the product mixture to obtain a first mass; adding water to the first mass for extracting unreacted chlorine gas and hydrogen chloride to obtain an aqueous suspension, and filtering the aqueous suspension to obtain a second mass; passing nitrogen through the second mass to extract residual water solution to leave behind a third mass; and agitating the third mass in a high-speed mixer together with a neutralizing agent, and optionally with a stabilizer and a processing additive to obtain dry thermally stable CPVC with thermal stability in the range of 1000 seconds to 1500 seconds.
    Type: Grant

  • Patent number: 9463451
    Abstract: A hydrogen transfer reaction may be more efficiently promoted by using a metal complex represented by Formula (2): (wherein, R1 to R8 are the same or different, and each represents a hydrogen atom, a substituted or unsubstituted alkyl group or the like; or wherein; R1 and R2, R2 and R3, R3 and R4, R4 and R5, and R5 and R6 are respectively bonded to each other to form a bivalent hydrocarbon group; R9 are the same or different, and each represents an alkyl group or cycloalkyl group; M is ruthenium (Ru) or the like; X is a ligand; and n is 0, 1 or 2). More specifically, the metal complex enables a hydrogenation reaction of various substrates having a stable carbonyl group or the like to be advanced with a high yield under mild conditions.

  • Patent number: 9272261
    Abstract: The present invention provides an organic-inorganic hybrid chiral sorbent for chiral resolution of various racemic compounds viz. racemic mandelic acid, 2-phenyl propionic acid, diethyl tartrate, 2,2?-dihydroxy-1,1?-binaphthalene (BINOL) and cyano chromene oxide with excellent chiral separation (enantiomeric excess, 99%) in case of mandelic acid under medium pressure column chromatography. These optically pure enantiomers find applications as intermediates in pharmaceutical industries.
