| titleOfInvention | Production of spherical particle |
| abstract | PURPOSE: To obtain porous spherical particles having excellent sphericity simply and economically with good reproducibility, by adding a soln. of both a cellulose org. acid ester and a gelling agent for said ester in an org. solvent to an aq. medium, causing the formed liquid droplets to gel and removing the gelling agent and the org. solvent. n CONSTITUTION: A cellulose org. acid ester (a) (e.g., cellulose triacetate) and 5W30vol% [based on the amount of the component (c)] gelling agent (b) for the component (a), selected from the group consisting of long-chain aliph. carboxylic acids and alcohols and aliph. esters of arom. carboxylic acids are dissolved in a water-insoluble org. solvent (c) such as methylene chloride or a mixture thereof with a small amount of methanol to obtain an org. solvent soln. (A). The component A is added to an aq. medium (B) such as water or a soln. of 0.2W10wt% water-soluble high-molecular material and/or 0.05W3wt% surfactant, etc. in water to form liquid droplets. The component (a) in the liquid droplets is caused to gel and the components (b) and B are removed from the formed spherical gel particles. n COPYRIGHT: (C)1988,JPO&Japio |
