Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an excellent cellulose acetate film without using any chlorinated organic solvent such as methylene chloride.
SOLUTION: The cellulose acetate film is produced by a process for cooling down a mixture of cellulose acetate with an organic solvent and containing 10-40 wt.% cellulose acetate to -100 to -10°C, wherein the cellulose acetate has 58.0-62.5% mean degree of acetylation and 250-400 viscosity-average degree of polymerization and the organic solvent substantially comprises acetone, a process for preparing the cellulose acetate solution by heating the cooled mixture to dissolve the cellulose acetate in the organic solvent to 0-50°C, a process for casting the cellulose acetate solution on a substrate and a process for volatilizing the solvent to form a cellulose acetate film.

Abstract: PROBLEM TO BE SOLVED: To obtain a cellulose ester having high releasability from a support and high spinnability and to obtain a method for producing the cellulose ester and to obtain the molded product of the compound. SOLUTION: The carboxyl groups of a raw material cellulose or a cellulose ester produced by acylation of the cellulose are blocked to produce the cellulose ester reduced in carboxy group concentration. The carboxy group concentration of the cellulose ester is e.g. ≤1 meq/100 g expressed in terms of cellulose. The molded product such as a film or a fiber can be formed by using the cellulose ester.

Abstract: PURPOSE: To obtain a filter material for tobacco smoke free from losing tobacco taste, excellent in wet disintegration and capable of reducing environmental pullution. CONSTITUTION: This filter material for tobacco smoke contains fibrillated fibrous cellulose ester. The fibrous cellulose ester has an average diameter of 15-250μm and a BET specific surface area of 0.5-4.5m /g. The content of cellulose ester in the material is e.g. >=20wt.%. The cellulose ester fiber is obtained e.g. by extruding a cellulose ester solution through a nozzle into a poor solvent for the cellulose ester. The cellulose fiber is fibrillated by shearing force generated in this process. The filter material can be used as a tobacco filter in e.g. fiber-, web- or sheet-form. An obtained taste of tobacco is good and the filter material is excellent in wet disintegration.

Abstract: PURPOSE:To separate an optical isomer of 3-hydroxypyrrolidines useful as an intermediate for producing medicines, agricultural chemicals, etc., from an optical isomer mixture of 3-hydroxypyrrolidines by forming a clathrate compound from an optical isomer of the optical isomer mixture and a host compound. CONSTITUTION:A mixture of optical isomers of 3-hydroxypyrrolidine expressed by formula I (R and R are H, 1-8C alkyl, arylalkyl, acyl, oxycarbonyl or carbamoyl) or their nitrogen or oxygen-protected compounds (e.g. 1-benzyl-3- hydroxypyrrolidine) is treated with a host compound such as an acetylene-based compound of formula II [Ar and Ar' are aryl; X is H, group of formula III, etc.; (n) is 1-3], a trans-1,2-di-substituted cyclic compound of formula IV (R is a group of formula III, etc.) or a biphenyl-based derivative of formula V (R is OH or a group of formula III). Thereby, a clathrate compound is formed from an optical isomer of the optical isomer mixture and the host compound to separate the objective optical isomer of 3-hydroxypyrrolidine of formula I from the mixture of these optical isomers.

CONSTITUTION:Optical resolution of an enantiomer mixture of asymmetric alcohol such as a compound of formula I, II, III or IV bearing atomic groups containing multiple bonds other than aryl and heteroaryl groups or its derivative is effected by means of a resolution agent which is composed of a polysaccharide or its derivative. Homoglycan of high regularity is preferred as a resolution agent and cellulose, amylose and beta-1,4-chitosan which are readily available in a pure form is more preferred. The resolution agent is used as such or immobilized on a carrier and used in a column for liquid or gas chromatography.
