DEFINITION

Classification: 435/72

Preparing compound containing saccharide radical:

(under subclass 41) Processes wherein the product synthesized contains a saccharide or polysaccharide, the monomeric units of which contain at least five-carbon atoms, or their reaction products wherein the carbon skeleton of the saccharide or polysaccharide of the unit is not destroyed.

(1) Note. Included herein is cellulose, derivatized cellulose, starch, derivatized starch, sugars, lignins, tannins, o-glycosides, n-glycosides, and s-glycosides.

(2) Note. Processes wherein the product synthesized is a degradation product which contains fewer than five-carbon atoms are not provided for in this subclass but are provided for in an appropriate subclass below.

SEE OR SEARCH THIS CLASS, SUBCLASS:

137, for sugar acids.

158+, for sugar alcohols.

262, for processes of liberation or purification of carbohydrates using a biochemical reaction.

SEE OR SEARCH CLASS 127, Sugar, Starch, and Carbohydrates, for the hydrolysis of carbohydrates including their conversion to sugar by means other than a microorganism or enzyme. Class 127 will provide for such processes using an enzyme or microorganism only where the hydrolysis by microorganism or enzyme is followed by steps of concentration, purification, or treatment (such

as crystallization) to make a sugar or syrup.

536, Organic Compounds, for the chemical manufacture or synthesis of sugar or carbohydrates by a process other than hydrolysis and the rearrangement of one carbohydrate to form another carbohydrate by means other than a microorganism or enzyme. Search
