2-pyrrolidone

2-pyrrolidone is colorless transparent liquid when temperature is higher than its melting point 23-25° C; But it is in crystal form once the temperature comes below than 23-25° C. 2-pyrrolidone is soluble with water, alcohol, ether, chloroform, benzene, ethyl acetate, carbon disulfide and most organic solvents in any ratio but it is insoluble in petroleum ether.

Sodium methoxide 30% solution & powder 99%

Sodium methoxide exists in two types: 99% pure powder & 30% solution. Sodium methoxide white powder is 4.2 class dangerous chemicals as it is easy to react with oxygen and it will divide into methanol and sodium hydroxide when meet moisture or air. It is soluble in methanol and ethanol. Sodium methoxide 30% solution is colourless to slightly yellowish, viscous liquid.

Triethyl Orthoformate (TEOF)

Triethyl Orthoformate, HC(OC2H5)3, also call Triethoxy methane, is a colorless transparent liquid which widely used in resin. It can be treated as a raw material of light sensitive material, also used in synthetic in dyes and cyanine dyes.

Camphor powder

Camphor is a flammable substance; It can burn in case of contacting oxidants. Ignition point of 50 degrees Celsius, 375 degrees celsius self ignition. Production facilities must be strictly observed. Workshop should be ventilated. When camphor on fire, please use the water mist, carbon dioxide, dry powder, sand to put off fire. The camphor steam in the air should not be more than 3 mg / cubic meter, otherwise, it may hurt people's nerves.

Sodium borohydride powder/granule

As a strong reducing agent, Sodium borohydride exists in 98% solid & 12% solution in appearance. For solid form, it is soluble in water and alcohol (ethanol & methanol). But we have to know one thing: Sodium borohydride is dangerous chemicals. It reacts readily with water and eaction may be violent. It is incompatible with water, oxidizing agents, carbon dioxide, hydrogen halides, acids, palladium, ruthenium and other metal salts, glass etc.

Benzaldehyde

Pure Benzaldehyde is colorless transparent liquid with almond-like odor. In China, we have naturally extracted Benzaldehyde, but the most common is synthetic benzaldehyde which is 99.5%min in purity. It is slightly soluble in water and soluble in almost all organic solvents such as benzene,alcohol,ether and chloroform etc.

Phenacetin powder

Phenacetin is glossy flaky crystalline powder, without odor, slightly bitter taste. Melting point 137-134. Stable in air, soluble in water, slightly soluble in ether, soluble in ethanol, chloroform. It is made by reduction of p-chloronitrobenzene via process of etherification, and acetylation reaction. Phenacetin is antipyretic and analgesic agent, suitable for fever, headache, neuralgia etc.

Nicotinamide

Nicotinamide is water soluble vitamins. It is easy to absorb by human and is widely distributed in the body. The excess part of Nicotinamide in the body can be excreted in urine by metabolism. As part of NADH and NADP +, Nicotinamide can promote the biological oxidation and motabolism of human body, especially the skin, digestive and nervous system.
