You are required to be on the same page. For this reason, cation-modified polymeric substances based on cellulose are highly safe, have good adsorption to hair and skin, feel good when used, and have good water retention properties, so they are extremely popular as the above-mentioned compounding agents. It can be said that it is a substance that has As a method for producing the above-mentioned cation-modified cellulose derivative, the method described in Japanese Patent Publication No. 45-20318 is the most common method.

。以下、本発明を詳細に説明する。However, in this method, the effective utilization rate of the cationizing agent is as low as about 20%, which is not only uneconomical, but also requires a large amount of cleaning agent to wash away the unreacted cationizing agent, making it difficult to close the business. Undesirable in terms of pollution. Also,
The transparency of the water-soluble substance obtained by this method is approximately the same as that of the original cellulose derivative solution, and is not modified during the reaction. On the other hand, as a result of extensive research, the present inventors have found that by treating the cellulose derivative with an alkaline substance before reacting the cellulose derivative with the glycidyl trialkylammonium salt, the reaction of the glycidyl trialkylammonium salt is possible. We have discovered a method for obtaining a cationically modified cellulose derivative that has a high yield rate, allows effective use of raw materials, suppresses the amount of detergent used to prevent pollution, and has good transparency with little insoluble matter. The present invention will be explained in detail below.

る。First, an ethylene oxide derivative of cellulose, a propylene oxide derivative of cellulose, or a mixed derivative thereof is treated and dispersed in a mixed solvent consisting of water and an inert organic solvent, and then an alkaline substance is added to this slurry.
Alkali treatment is performed at a temperature of ~80°C for about 15 minutes to 3 hours.

ースが一般的である。Subsequently, a glycidyl trialkylammonium salt is added to the treated solution to cause the above derivative to react with the glycidyl trialkylammonium salt. After the reaction is completed, the solution is then neutralized and washed with an acid solution or a mixture of an acid and an inert organic solvent in accordance with a conventional method to obtain a slurry. The residue is dried to obtain a cationically modified cellulose derivative. The ethylene oxide derivative of cellulose used in the present invention is generally hydroxyethyl cellulose, and the propylene oxide derivative of cellulose used is generally hydroxypropyl cellulose.

撹拌が困難となつて反応性を阻害する。The number of moles of ethylene oxide or propylene oxide added to these derivatives is usually 1.5 to 3. However, as the number of moles added increases, hygroscopicity increases, making it unfavorable for handling. .5 is the most desirable. The amount of water in the mixed solvent used in the present invention should be sufficient to uniformly decompose the alkaline substance acting as a catalyst during the reaction process, but if the amount is too small, a completely heterogeneous reaction may occur. On the other hand, if the amount is too high, the cellulose derivative will dissolve and the viscosity of the reaction system will increase significantly, making stirring difficult and inhibiting the reactivity.

ース１単位に対して０．２〜１．５倍モルである。Therefore, the amount of water is usually 0.5 to 5 parts by weight, preferably 0.8 to 1.2 parts by weight, per 1 part by weight of the cellulose derivative. Examples of the inert organic solvent in the mixed solvent used in the present invention include isopropanol, Sec-butanol, tert-butanol, etc., and the amount thereof is usually 2 to 10 times the weight of the cellulose derivative, preferably 4 to 7 times the weight of the cellulose derivative. It's twice as heavy. Examples of the alkaline substance used in the alkaline treatment of the present invention include lithium hydroxide, sodium hydroxide, potassium hydroxide, and the like. The amount of the alkaline substance added is 0.05 to 0.3 moles per unit of anhydrous glycose of the cellulose derivative. The reason for this is that if the amount of the alkaline substance added is less than 0.05 times the mole, the desired effect cannot be sufficiently achieved, while if the amount exceeds 0.3 times the mole, no improvement in the effect will be seen. Otherwise, a large amount of salt is produced as a by-product during neutralization, which is undesirable. Examples of the glycidyl trialkylammonium salts used in the present invention include glycidyl trimethyl ammonium chloride, glycidyl triethylammonium chloride, glycidyl trimethyl ammonium fluoride, and glycidyl trimethyl ammonium iodide, and the amount usually added is The nitrogen content of the obtained cation-modified cellulose derivative is in a range of 0.5 to 2.5%, that is, the molar amount is 0.2 to 1.5 times per unit of anhydroglucose of the cellulose derivative.
