N,N-dimethyl-3,5-methylene piperidinumchloride - Reference Information
| LogP | -2.49 at 20℃ and pH7 |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| preparation method | A preparation method of a cationic monomer dimethyl diallyl ammonium chloride, characterized in that: under the temperature of 15~20 ℃, the weight ratio of 33% dimethylamine and allyl chloride is 1: 1.2, and the allyl chloride is added dropwise, it is added dropwise to the solution containing 33% dimethylamine, strong basic resin and phase transfer catalyst; After the dropwise addition of allyl chloride is completed, the temperature is raised to about 50 ° C. And the mixture is refluxed for 3-8 hours, when the pH was about 8, the reaction was stopped; Then, the reaction was separated and distilled under reduced pressure to obtain dimethyldiallylammonium chloride. The strongly basic resin may be a strongly basic styrene anion exchange resin, and the amount of the strongly basic resin to be fed can meet the exchange capacity, and the phase transfer catalyst is tetraethylammonium bromide or tetraethylammonium chloride. |
| Application | diallyldimethyl ammonium chloride is widely used in oilfield additives, sewage treatment, printing and dyeing, papermaking, daily chemical and pharmaceutical, textile, leather and other industries. used in water treatment, paper industry, printing and dyeing industry, resin synthesis and so on The compounds prepared under various PH conditions have excellent salt resistance and alkali resistance; for free radical initiators (such as peroxides, azo compounds) such as polymerization; Cationic monomer, can be homopolymerized or copolymerized with other vinyl monomers, to the polymer into the quaternary ammonium group, thus has a very strong polarity and affinity for anionic substances |
