DADMAC as a cationic monomer by homopolymerization or copolymerization to form polymers. The polymer can be used as superior non-formaldehyde fixing agent in textile dyeing and finishing auxiliaries to form a film on the fabric to improve the color fastness. It can be used as retention and drainage aid in papermaking auxiliaries, and paper anti-static ; Can be used for decolorization, flocculation and purification in water treatment, efficient and non-toxic; in household chemicals, can be used for shampoo combing agent, wetting agent and antistatic agent; available in oilfield chemicals In the flocculant, plugging agent. Its main role is neutralization, adsorption, flocculation, purification, decolorization, especially as a synthetic resin modifier, given the conductivity, antistatic properties.
The 40% aqueous solution of dimethylamine 330kg was added to a reaction kettle with a circulating cooling water system, cooled to below 20 ℃, and then slowly added sodium hydroxide solution 125kg, until the sodium hydroxide solution was added, cooled to 10 ℃ or less. Then from the allyl chloride feed tank slowly add allyl chloride 492kg, when allyl chloride was added to the amount of 1/3, the system temperature was raised to 15 ℃; when allyl chloride was added to 2/3 When the system temperature is 20 ℃. Add the remaining allyl chloride below 25 ° C until the addition of allyl chloride, the system was warmed to 45 ° C, at this temperature reflux for 6 ~ 8h. After the reaction time has been reached, the resulting reaction product is cooled to below 15 ° C, and the resulting sodium chloride is removed by filtration. The filtrate is transferred to a still pot and concentrated under reduced pressure. After concentration to a certain extent, hot filtered to remove by-produced chlorine Sodium. In the resulting filtrate by adding a certain amount of distilled water to control the solids content of more than 60%, the material, packaging, that was polymerization grade dimethyl diallyl ammonium chloride solution.
