A method of preparing a composition comprised of a glycoside having a cationic-substituted glycosyl moiety is provided. A cationic starch derivative is reacted with a monohydric alcohol to form cationic-substituted glycosides. Cationic starch derivatives include the tertiary amino, imino, quaternary ammonium or phosphonium, or tertiary sulfonium starch derivatives. Compounds generally characterized as glycosides having cationic-substituted glycosyl moiety are also claimed.

Substituted glycoside compositions

Remarkably good surfactancy characteristics are exhibited by alkylene oxide (e.g., ethylene oxide, propylene oxide, etc.) adducts of relatively low degree of polymerication, (D.P.), long chain glycoside compositions of the sort which are predominantly composed of long chain monoglycoside species and in which the types and relative proportions of any long chain polyglycoside species contained therein are such that the average degree of polymerization of such long chain glycoside constituents is less than 2.7. The subject low D.P. long chain polyglycoside alkylene oxide adducts exhibit surfactancy and/or detergency characteristics at least about as good as, and in some respects substantially better than, the corresponding alkylene oxide adducts of higher D.P. long chain glycoside materials.

New anionic derivatives of mono and polyglycosides which are surface-active agents are described which anionic derivatives have the general formula ##STR1## wherein G is a glycosyl moiety which is derived from a reducing sugar selected from the group consisting of fructose, glucose, mannose, galactose, talose, gulose, allose, altrose, idose, arabinose, xylose, lyxose, ribose or mixtures thereof,

Ionic derivatives of alkyl mono and polyglycosides

The transfer printability of fabric materials containing at least a minor proportion of cellulosic or natural proteinaceous fibers such as, for example, cotton, rayon, cellulose acetate, wool, silk, etc. is notably improved by a treatment in which said fabric material is impregnated with certain glycoside reagents. Especially preferred glycoside reagents for use in such treatment are C.sub.2 -C.sub.6 alkyl monoglucosides.

Enhanced transfer printability treatment method and composition

A glycoside compound containing one or more fatty acid ester or ether groups is used as a mold release agent in the production of molded articles from polymeric resinous materials. Said mold release agent can function as either external or internal mold release agent. The molded article also has improved tie coating properties.

Glycoside-containing polyester products having improved color characteristics are provided by a polyester preparation process in which a polyol reactant containing at least a minor proportion of a glycoside reactant is reacted with a lower alkyl ester of a polybasic acid. The color characteristics of such products are notably improved relative to that which is obtained when said reaction is instead conducted using the corresponding polybasic acid or anhydride in place of the indicated lower alkyl ester thereof. The color improvement benefits of the present invention are particularly pronounced and dramatic when the polybasic acid component of the desired polyester product comprises an aromatic polybasic acid and when a lower alkyl ester of said aromatic polybasic acid is employed in the reaction in place of the aromatic acid itself.

Glycoside-containing polyester preparation process

The present invention relates to the preparation of aldoside mixtures, recovering at least a portion of one aldoside component therefrom and reusing the remaining portion of the aldoside mixture to prepare additional aldoside. The aldoside mixture may be prepared by slurrying the carbohydrate in alcohol and passing the slurry through a continuous reactor at an elevated temperature under fluid pressure in the presence of an acid catalyst. The resultant aldoside mixture may then be partitioned into a mother liquor portion and an aldoside portion by selectively recovering at least a portion of one aldoside from the crude aldoside mixture with the remaining mother liquor being recycled. Crude glycoside mixtures prepared from starch and methanol slurries are suitable substrates for selectively recovering methyl-alpha-D-glucopyranoside. The methyl-alpha-D-glucopyranoside may be easily crystallized and recovered from the glycoside mixture because of its lower solubility in methanol. The resultant mother liquor (rich in the remaining components of the glycoside mixture) in combination with freshly added starch and methanol provides a reaction medium which optimizes methyl-alpha-D-glucopyranoside production.

Method of using recycled mother liquors to produce aldosides

A continuous process for making alkyl aldosides from polysaccharides and more particularly mixed alkyl glycosides from starch by direct alcoholysis. A polysaccharide, such as starch, is slurried in an alcohol and passed through a heated, confined zone under pressure in the presence of an acid catalyst to form a mixed alkyl aldoside. The alcohols which may be used include methanol, ethanol, propanol and butanol, their isomers and mixtures thereof. Higher alkyl glycosides are surfactants and, in some instances, it is advantageous to use higher alcohols, such as decyl and dodecyl alcohols, to obtain particular surfactant properties in the resulting alkyl glycosides. Mixed alkyl glycosides are useful in detergent applications, and as backbone polymers in polyurethane foams.

Continuous process for making alkyl aldosides from starch or other

An improved method for thinning starch in the granular state employing hydrogen peroxide and metal ion catalysts in an aqueous suspension, free of buffer additions. The thinning action proceeds in acid pH to the desired viscosity level, and is stopped by the addition of sodium metabisulfite, or other reducing agent to remove residual hydrogen peroxide. The aqueous suspension is then neutralized, and the usual purifying and drying steps are effected on the granular product.
