摘要

降低天然材料和合成材料及其制品的可燃性是自然保护和环境保护的主要问题之一。为了获得阻燃剂等不燃材料,本工作中使用了正磷酸钠盐、尿素、硫脲及其单甲基衍生物以及n-单甲基丙烯酰胺。上述化合物的合成反应是在少量水的存在下进行的。尿素与正磷酸单钠盐反应时,释放出氨和СО2。硫代氨基脲与正磷酸单钠盐反应时,除氨和CO2外,还部分释放出硫化氢,本文介绍了硫化氢的形成机理。

NEW TYPES OF FLAME RETARDANTS BASED ON PHOSPHATE DERIVATIVES
One of the main problems of nature conservation and protection of the environ-ment is the reducing of flammability of natural and synthetic materials as well as products based on them. In order to obtain non-combustible materials such as flame retardants, monosodium salt of orthophosphoric acid, urea, thiourea and their mono-methylol derivatives, as well as N-monomethylol acrylamide were used in this work. The reaction for the synthesis of the mentioned compounds was carried out in the presence of a small amount of water. During the reaction between urea and monosodium salt of orthophosphoric acid, ammonia and СО2 were released. In the case of the reaction of thiocarbamide with the monosodium salt of orthophosphoric acid, in addition to ammonia and CO2, hydrogen sulfide is partially released, the formation mechanism of which is presented in the work.
