Abstract

PURPOSE:To prepare the titled compound useful as a synthetic raw material of a surface active agent, adhesive and amineimide compound, and pesticide, etc., easily, in high yield and purity, by reacting a tertiary amine with the reaction mixture of ammonia water and sodium hypochlorite. CONSTITUTION:The reaction mixture of ammonia water and sodium hypochlorite is obtained by adding sodium hypochlorite to ammonia water while cooling the system to 0 deg.C or below. The reaction mixture is made to react with a tertiary amine (e.g. trimethylamine, N,N,N'N'-tetra-methylethylenediamine, N-methylmorpholine, triethylenediamine, etc.) at -10-+20 deg.C to obtain the objective compound. The reaction is carried out by adding the reaction mixture dropwise to the tertiary amine (or its aqueous solution). The amount of the tertiary amine is nearly equimolar to the chloroamine contained in the reaction mixture, or 0,9-1.1 times mole of the chloroamine.

However, in the method of 1), when alkyl iodide, bromide, )V rate, etc. are used as reagents, tria-ki/&/hydrazinium can be obtained almost quantitatively; When clophyte is used, a large amount of trialkylhydrotuzine is produced as a by-product. Further, both the double decomposition method (2) and the neutralization method (3) cannot be said to be industrially advantageous methods in that they use silver compounds. In addition, the method of 4) in which the chloramine paste obtained by the reaction of ammonia gas and chlorine gas is reacted with a tertiary amine has a high yield of chloroamine paste, but requires the use of an excess of amine. ,
It is difficult to remove ammonium chloride produced by the reaction between ammonia gas and chlorine gas, and as a result, the flow rate of chlorine gas cannot be increased, making it unsuitable for mass production. Also,
As an improved method for this reaction, a tertiary amine and ammonia are dissolved in isopropyl γμ co-μ! A method has been proposed in which circular ring gas is injected diluted with nitrogen gas. However, with this method, it is necessary to use approximately twice the amount of tertiary amine as compared to chlorine gas, and the flow rate of chlorine gas cannot be increased, so it cannot be said to be an excellent method from an industrial perspective. .

The present inventors investigated an industrially advantageous method for producing quaternary human fusinium chloride, and used a reaction mixture of aqueous ammonia and an aqueous solution of sodium hypochlorite to neutralize, extract, Surprisingly, it was found that when reacted with a tertiary amine in an aqueous medium without taking any purification measures such as isolation, quaternary and dophnium chlorides were produced in high yield. Surprisingly, the conventional method using chloroamine gas
Whereas a large excess of tertiary amine was required relative to chloroamine, in the reaction using the above reaction mixture in an aqueous solvent, the chloroamine present in the reaction mixture was It has been discovered that the desired product can be obtained in high yield simply by using an amine. Conventionally, methods have been known in which ammonia water and sodium hypochlorite aqueous solution are reacted to form an aqueous solution containing chloroamines or a concentrated solution thereof, and chloroamines are extracted from the solution with a solvent such as ether. The chloroamine thus isolated is an extremely unstable compound and cannot be said to be suitable as an industrial raw material. In addition, the above chloroamine-containing aqueous solution can be used directly and with doralin derivatives, such as non-targeted sia μ

The reaction can be carried out by dropping a reaction mixture of aqueous ammonia and sodium hypochlorite onto a tertiary amine (usually in water), or vice versa. A method of dropping it into the reaction mixture with sodium hypochlorite may also be used. The reaction usually completes in 10 minutes to 2.3 hours, and after the reaction is completed, it is neutralized using a commonly used mineral acid such as caustic soda ft hydrochloric acid present in the system. After the water has been evaporated, the target product, quaternary human fusinium clophyte, is obtained using an organic solvent such as ethanol, n-globanol, in-propanol, n-butano-fi/chloroform, etc. Extract.
