摘要： A method of recovering polyvinyl chloride from a waste comprising polyvinyl chloride which comprises: the step of removing the insoluble solid matter from a heated mixture of the waste and a solvent in which polyvinyl chloride is soluble; the step of contacting the residual solution with heated water to remove the solvent and thereby precipitate the polyvinyl chloride in the water; and the step of separating the polyvinyl chloride precipitate from the water. Thus, polyvinyl chloride can be continuously recovered from a waste comprising polyvinyl chloride.

摘要： A method for producing a high purity 2,6-dimethylnaphthalene by subjecting a dimethylnaphthalene-containing mixture which contains 2,6-dimethylnaphthalene to crystallization by cooling and then to solid-liquid separation, and washing the resultant solid with a solvent, characterized in that the solid-liquid separation step comprises expression filtration. Preferably, a pressure of 10 kg/cm2 or higher is employed for the expression filtration. The method can be used for producing a high purity 2,6-dimethylnaphthalene from a DMN mixture containing 2,7-dimethylnaphthalene in an amount of 5 mass % or more as a starting material, and further for producing a high purity 2,6-dimethylnaphthalene from a DMN mixture having a 2,6-dimethylnaphthalene content of 25 mass % or less as a starting material.
