化学的特性
Centralite II, also known as 1,3-Dimethyl-1,3-diphenylurea, is a white to grey crystalline powder that is soluble in water, alcohol, acetone, and chloroform. This substance is commonly used as a burning rate moderator and stabilizer for smokeless powder, as well as a plasticizer for celluloid.
使用
Detection of Methyl Centralite (MC) as gunshot residues (GSR) has been developed.
説明
1,3-Dimethyl-1,3-diphenylurea for Stabilizer and propellant, and production of intermediates of organic chemicals.
使用
1,3-Dimethyl-1,3-diphenylurea (methyl centralite) is a stabilizer in different types of ammunition. This compound is organic gunshot residue. It is the characteristic compound for which forensic analysts test determining if a person has discharged a firearm[1-2].
製造方法
1,3-Dimethyl-1,3-diphenylurea can be synthesized through the reaction of methylaniline and phosgene.
主な応用
Centralite II can be used as a stabilizer for smokeless powder, explosives, nitrates and smokeless fuels, as well as intermediates for fine chemicals.
合成
To a 10 mL Schlenk tube equipped with a magnetic stirring bar was charged with arylcarbamoyl chlorides (0.2 mmol, 1.0 equiv), and KHCO3 (40 mg, 0.4 mmol), and then Pd(PPh3)4 (0.01 mmol, 11.56 mg) were added. Finally, 1,4-dioxane (1.0 mL) was added to the mixture via syringe at room temperature under N2. The tube was sealed and put into a preheated oil bath a 100 °C for 48 h. The mixture was cooled to room temperature, quenched with water (5 mL), and diluted with ethyl acetate (5 mL). The layers were separated, and the aqueous layer was extracted with 2 × 5 mL of ethyl acetate. The combined organic extracts were dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The crude product of 1,3-dimethyl-1,3-diphenylurea was purified by flash chromatography on silica gel (H), using 30-35% ethyl acetate/petroleum ether as the eluent.
貯蔵
Store in original tightly closed containers in a dry, cool and well-ventilated area.
