| titleOfInvention | NaHSO3Preparation method of ethyl cellulose microcapsule |
| abstract | The invention relates to NaHSO 3 A preparation method of ethyl cellulose microcapsules, which relates to the technical field of slow release microcapsules; the method specifically comprises the following steps: s1) preparing an ethyl cellulose solution; s2) preparation of NaHSO 3 A dispersion liquid; s3) under the condition of rapid stirring, dispersing NaHSO into the mixture 3 Dropwise adding cyclohexane into the ethyl cellulose solution to separate out the ethyl cellulose from the ethyl cellulose solution and coating the ethyl cellulose with NaHSO 3 Preparing microcapsule suspension on the surface of the particles; carrying out vacuum filtration to obtain a filter cake, and carrying out freeze drying to obtain the microcapsule; s4) adding the filtrate into water, and introducing CO 2 Separating to obtain cyclohexane and N, N-dimethylcyclohexylamine protonated aqueous solution, and collecting for recycling; s5) introducing N into the aqueous solution 2 And separating to obtain the N, N-dimethyl cyclohexylamine, and collecting for recycling. The preparation method disclosed by the invention is simple, saves the cost and has little pollution to the environment. |
