The influence of side chain monomers on the synthesis and properties of piperazine based triazine charring agent was studied. The results show that side chain monomers have a great influence on the synthesis of the charring agent. The stronger the hydrophilicity of side chain monomers is, the more the water-solubility of the charring agent is and the lower the yield is. The weak nucleophilicity of aromatic amines results in higher chlorine content and lower yield of charring agents. Side chain monomers also have significant effects on the thermal stability and flame retardancy of the charring agents. The charring agent with ethanolamine has the best thermal stability, followed by the charring agent with morpholine or aniline, butylamine, diethanolamine and ammonia; the more hydroxyl groups the side chain monomers have, the better the flame retardant effect of the corresponding charring agent is. The side chain monomers without hydroxyl groups result in the poor flame retardant effect of the corresponding charring agent, and the charring agent with ammonia has the worst flame retardant effect. The side chain monomers have little effect on the mech. properties of the flame retardant PP. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Name: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Name: 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine
