Product Detail

Pls input...

Items	Specifications
Stroma	Methyl Alcohol
Form	Liquid
Storage conditions	Refrigerate at 2-8°C and store in an airtight and dark condition. It should be equilibrated at room temperature (20±3℃) before use, and shaken well to ensure uniformity. Ampoules should be used immediately once opened, and cannot be used as a standard material after being melted again. Strictly prevent contamination during use.
Applications	This reference materialis mainly used for the content of Benzene-based plasticizers in food, environment, packaging materials and other fields, residual detection and analysis of instrument calibration, analytical method evaluation and laboratory quality control during the detection process.
Reference material	Air and Waste Gas Monitoring and Analysis Methods 4th Edition, Water and Waste Gas Monitoring and Analysis Methods 4th Edition - State Environmental Protection Administration.
Physical and chemical properties	Properties: colorless transparent liquid with special smell. Melting point -55 ℃, boiling point 386.9 ℃,222-230 ℃(0.53kPa), relative density 0.986(20/4 ℃), refractive index 1.4852, flash point 217 ℃, ignition point 241 ℃, viscosity 81.4mpa s, vapor pressure (200 ℃)176Pa. The solubility of the product in water is less than 0.01% at 25 ℃, and the solubility of water in the product is 0.2%. Soluble in most organic solvents and hydrocarbons, slightly soluble in glycerin and ethylene glycol. It has good compatibility with most industrial resins. Partially compatible with acetic acid cellulose and polyacetic acid vinyl ester. This product is the most widely used plasticizer with the largest yield, and is the most important variety of phthalic diformic acid ester plasticizer. This was followed by dibutyl phthalate (DBP,[87-74-2]), diisodecyl phthalate (DIDP,[19269-67-1]) and diisooctyl phthalate (DIOP,[27554-26-3]). In the field of plasticizers, if not specified, "octyl ester" is customary to refer to 2-ethylhexyl ester. Phthaleneformic acid di (2-ethylhexyl) ester (DOP) is customarily called phthaleformic acid dioctyl ester. Its isomer is except for phthaleformic acid diisooctyl ester (DIOP), Phthaleneformic acid din-octyl ester (DnOP) is also a practical plasticizer, in addition to phthaleformic acid disecondary octyl ester (DCP). Preparation method: The amount of plasticizer is very large, and there are many varieties. At present, the development trend of plasticizer production technology is, on the one hand, the continuous large-scale production of the main plasticizer, on the other hand, the multi-variety, small-batch intermittent production of special plasticizers. The consumption of phthalic acid esters accounts for about 80% of the total amount of plasticizers, and the production volume is very large, so there is a continuous large-scale production centered on phthalic acid dioctyl ester. Phthalenediformic acid esters are industrially prepared by esterification of phthalic anhydride and corresponding alcohols in the presence of acidic catalysts such as sulfuric acid and p-toluenesulfonic acid. The amount of acidic catalyst is generally 0.2-0.5% based on phthalic anhydride. The esterification reaction is carried out by phthalic anhydride and 2-ethylhexanol (isooctanol) under the catalysis of sulfuric acid or titanate, stannous oxide, aluminate and other non-acidic catalysts, and the esterification liquid is neutralized, washed with water, Alcohol removal, decolorization, pressure filtration to obtain the finished product. Raw material consumption quota: phthalic anhydride 383kg/t, 2-ethylhexanol (95%)671kg/t, sulfuric acid 6kg/t, soda ash 10kg/t. Uses: This product is the most widely used plasticizer. In addition to cellulose acetate and polyethylene acetate, it has good compatibility with synthetic resins and rubbers used in most industries. This product has good comprehensive performance, good mixing performance, high plasticizing efficiency, low volatility, good low temperature flexibility, water extraction resistance, high electrical performance, good heat resistance and weather resistance. As a main plasticizer, this product is widely used in the processing of various soft PVC products, such as films, sheets, artificial leather, cable materials and molded products. The product is non-toxic and can be used for packaging materials in contact with food, but it is not suitable for fatty food packaging materials because it is easy to be extracted from fat. It can also be used for nitrocellulose paint to make the paint film have elastic high tensile strength. In a variety of synthetic rubbers, this product also has a good softening effect. In addition, DOP is also used as a condensing agent, anti-wear agent, organic solvent, and gas chromatography fixative.
