Molecular formula : C20H26O4
MW : 330.43
CAS No. :84-61-7
nature : white amorphous powder. The temperature 64-66 ° C, relative density of 1.20 (30/26 ° C). The majority of soluble organic solvent, in the heat of petrol and mineral oil had completely dissolved, micro-soluble glycol and certain types of amines, in a 25 ° C water solubility of less than 0.01%.
Preparation : phthalic anhydride and cyclohexanol derived esterification. Raw material consumption (kg / t) phthalic anhydride 500 cyclohexanol 670
purposes : the goods are phthalate plasticizer esters. These plasticizers varieties, production, the total output of the plasticizer about 80%, with a full performance, in general, as a plasticizer for use. The phthalate esters, 2 - phthalate ester (DOP), the most widely used in China plasticizer about 45% of the total. Phthalate Dicyclohexylperoxydicarbonate as PVC, acrylic resin, polystyrene, nitrocellulose resins, etc. The main plasticizer, with moisture, and other plasticizers used, dense contraction products can prevent water vapor through volatilization and plasticizers. The goods containing plastic products surface finish and feel good. The general consumption goods accounted for the total amount of plasticizer 10-20%, the amount should not be too large, otherwise products increased hardness. The materials can be improved resin in the heat processing of mobility. The synthetic resin adhesive, which could enhance its adhesion strength, durability and oil resistance. In addition, the products are also used cellulose nitrate and some natural resin, moisture-proof coatings can be created. Low toxicity of the goods, the goods containing 25% of the dose of olive oil directly rats after oral exposure, 24 cases with no deaths, within 7 days of the LD50 of 30ml/kg. This is determined by the mixing 10mg/kg dose to feed, feeding rats eight four generations, the growth of experimental animals, breeding, nursing no any abnormal, but also non-carcinogenic.
