摘要： Hydrazine is utilized for preventing side reactions during the preparation and storage of polyisocyanates partially blocked with hydroxy amines which are utilized for the introduction of basic functional groups into organic coating compositions which are deposited cathodically in an electrodeposition process. The inhibiting compound is used in the form of hydrazine hydrate at a level of from about 50 to 5000 ppm calculated on the amine used in the reaction.

摘要： The present invention is directed to a purification method for purifying a fluorine-containing polymerizable monomer of the formula (1), in which the fluorine-containing polymerizable monomer is purified by distillation in the coexistence of a phenolic compound A such as 6-tert-butyl-2,4-xylenol and a phenolic compound B such as 2,2′-methylene-bis(4-methyl-6-tert-butylphenol). By the combined use of the phenolic compound A and the phenolic compound B, it is possible to significantly suppress polymerization or oligomerization of the fluorine-containing polymerizable monomer even during industrial-production-scale distillation and efficiently purify the fluorine-containing polymerizable monomer by distillation.

摘要： A novel process can be used for purifying methyl methacrylate (MMA) contaminated with low-boiling components by distillation, where the process involves producing MMA by oxidative esterification, and a crude product containing methyl propionate (MP), methyl isobutyrate (MIB), and methacrolein (MAL) as low-boiling components. The process is compatible with MMA produced from C2-based methacrolein containing the low-boiling components specified.

摘要： Provided is a plasticizer composition, a resin composition and a method of preparing the same. The plasticizer composition comprises two or more kinds of cyclohexane 1,4-diester-based materials; and a citrate-based material. Particularly, a plasticizer capable of improving physical properties such as plasticizer efficiency, migration, tensile strength, elongation rate, stress migration and light resistance, which are required for sheet formulations, when used as a plasticizer for a resin composition by improving poor physical properties generated due to a structural limitation thereof, and a resin composition including the same are provided.

摘要： A method for manufacturing and a method for decolorizing dioctyl terephthalate are provided. The decolorizing dioctyl terephthalate includes: providing an unpurified dioctyl terephthalate; mixing the unpurified dioctyl terephthalate with a reducing agent and an adsorption medium to obtain a first decolorizing product; and mixing the first decolorizing product with a decolorizing adsorbent material to obtain a second decolorizing product. The method for manufacturing dioctyl terephthalate includes: a transesterification step, an alkaline washing and neutralization step, a redox step, a decolorization step and a stripping step; the decolorizing adsorbent material has an acid value between 0.1 and 2 mg KOH/g, a relative humidity between 2 and 10%, and a fineness between 80 and 100 cm2/g.
