Abstract
Cellulose is esterified with a reaction mixture containing butyric acid a propionic acid, and/or lower fatty acid anhydride. For example, when propionic acid is used, one of the following anhydrides could be employed, viz., acetic anhydride, chloracetic anhydride, methoxy-or ethoxy-acetic anhydride, and when butyric acid is used, propionic anhydride, chlorpropionic anhydride, alkoxy-propionic anhydride, acetic anhydride or its derivatives may be present. The esterification-impelling anhydride may or may not itself also contribute acyl groups to the product. In this way mixed esters, e.g., cellulose propionate-butyrate, cellulose acetate-propionate, cellulose acetate-butyrate, and cellulose acetate-propionate-butyrate may be obtained. The following Examples are given:--(1) Cotton is esterified in a bath comprising propionic acid, acetic acid, acetic anhydride, and zinc chloride, to produce a mixed acetate-propionate. (2) Cotton is treated with a mixture comprising butyric acid, acetic anhydride, acetic acid, and magnesium perchlorate trihydrate. (3) Cotton is esterified in a mixture comprising propionic acid, acetic acid, acetic anhydride, and sulphuric acid. (4) Cotton is esterified in a bath comprising propionic acid, acetic anhydride, ethylene dichloride, and sulphuric acid. (5) Cotton fibres are acylated so as to retain their fibrous structure by pretreating with propionic acid and perchloric acid, and reacting with a mixture of carbon tetrachloride and acetic anhydride. The products may be utilized in the production of filaments, films, lacquers, and the like.
