The solubility of anhydrous ethanol (C2H5OH) and ethyl ether were 1.26% and 0.01% respectively at 13ºC. Soluble in liquid ammonia, hot water, ethanol, acetone hydrate, dimethylformamide, insoluble in ether, insoluble in benzene and chloroform. Relative density (D254)1.40. The melting temperature of 209.5 ºC. It is stable when dry. Don't burn. Low toxicity, half lethal dose (mice, oral)>4000mg/kg. The maximum allowable concentration in the air is 5mg/ M&SUp 3; .

PRODUCT USAGE

[Purpose 1]

It is the raw material of melamine and the intermediate of synthetic medicine, pesticide and dye

[Purpose 2]

Used in organic synthesis and resin synthesis, as well as as vulcanization accelerator and hardener

[Purpose 3]

It is the raw material for melamine production. It is also an intermediate of medicine and dyes. In medicine, it is used to produce guanidine nitrate, sulfonamides, etc. It can also be used to produce thiourea, guanidine, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardening agent, printing and dyeing fixing agent, artificial leather filler and adhesive, etc.

[Purpose 4]

The main uses of dicyandiamide are: (1) As the raw material of guanidine salt and melamine. The reaction of dicyandiamide with acid can produce various guanidinium salts. Benzyl melamine diamine obtained from the reaction of dicyandiamide and phenylnitrile is an intermediate of coatings, laminates and molding powder. (2) Used as dye fixing agent, dicyandiamide resin prepared by reaction of dicyandiamide and formaldehyde can be used as dye fixing agent. (3) Dicyandiamide fertilizer and dicyandiamide compound fertilizer can control the activity of nitrifying bacteria, regulate the transformation rate of nitrogen fertilizer in the soil, reduce the loss of nitrogen, and improve the use efficiency of fertilizer. (4) As an intermediate of fine chemical industry. In medicine, it is used to produce guanidine nitrate, sulfonamides, etc; It is also used to produce thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardening agent, artificial leather filler, adhesive, etc. The medical intermediate 5-azacytosine can be obtained by the reaction of dicyandiamide and formic acid.

[Purpose 5]

Verification of cobalt, nickel, copper and palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, resin synthesis.

PACKAGING & STORAGE

It should be placed in a cool and dry place indoors to avoid sun and rain.
