Abstract: The present invention refers to dicyanovinylsubstituted furan derivatives, processes for their production and their application. The new furan derivatives are represented by the general formula ##STR1## wherein x.sup.1 and x.sup.2 are equal or different and stand for H, alkyl, alkenyl, aryl, halogen, NO.sub.2 or CN.In the general formula I, n may be 0 or 1. In case of n=0, A means e.g. --CH.sub.2 OR.sup.1 (with e.g. R.sup.1 .dbd.H, alkyl or aryl).The compounds according to this invention can be used directly or in the form of their cycloadducts in several applications of electro-optical fields, e.g. for the manufacture of optical data recording systems or organic (electron) conducting materials or electron-transfer catalysts.

Abstract: There is disclosed a process for the manufacture of sugar-free dietetic and/or teeth-sparing chocolates with the preceding separate production of a sugar-free crumb and its further processing with its use of the chocolate constituents otherwise usual and subsequent tumbling into chocolate.

Abstract: The invention concerns a process for production of L-arabionose in crystalline form. Starting material are extracted sugar beet pulp or other L-araban containing plant materials. These are heated in an autoclave as an aqueous suspension in the presence of Ca(OH).sub.2. The so obtained solution is chromatographed on a cationic exchanger in the Ca-form. The araban containing fraction is hydrolyzed after adding H.sub.2 SO.sub.4, neutralized and rechromatographed on a cationic exchanger in Ca-form. After concentrating the arabinose containing fractions L-arabinose is obtained in form of crystals by cooling crystallization.

Abstract: The present invention refers to a process for preparing 5-hydroxymethylfurfuraldehyde, which is also called HMF. This compound was yet prepared by dehydration of fructose-containing carbohydrates in the presence of various catalysts. Nevertheless, the separation of HMF from starting material, by-products and organic solvents was difficult and disadvantageous, especially by the presence of organic solvents. Surprisingly, it came out, that it is possible, to separate 5-hydroxymethylfurfuraldehyde from reaction mixtures, which are obtained by reactions of saccharides with an acid catalyst, in great purity and good yield with exclusive utilization of water as solvent, by means of ion exchangers, and to crystallize it out from chromatographic fractions.

Abstract: Isomaltulose (6-0-alpha-D-glucopyranosido-D-fructose) is produced by passing a pure sucrose solution through a reactor containing dead, immobilized cells of an isomaltulose-forming microorganism. The sucrose solution preferably contains 45 to 75% by weight sucrose and has a temperature of 45.degree. to 65.degree. C.

Abstract: The invention relates to derivatives and reduction products of D-glucopyranosyl-alpha(1.fwdarw.5)-d-arabinonic acid, having the general formula: ##STR1## wherein X is one of the following groups: --COOM, --COOR', CONH.sub.2 or --CH.sub.2 OH, where M is an alkali metal and R' is an alkyl group; and where R is a hydrogen atom or an acyl group. The compounds of formula (I) include compounds in which the arabinonic acid chain is closed in a lactone ring.A method for producing the derivatives and reaction products is described, and uses therefor are also provided.

Abstract: Process for obtaining beet pulp of high dry-solids content from a sugar extraction process by mechanically pressing the pulp, mixing salts of polyvalent cations, an acid or both with the pressed pulp, further pressing the admixture and thermally drying the admixture. The salts of the polyvalent cations are preferably calcium chloride, aluminum chloride and ferric chloride and are added in an amount of from 0.5 to 10%, preferably from 1.5 to 4%, relative to the pulp dry-solids content. The liquid from the second pressing can be concentrated by evaporation and at least part can be recycled to produce the initial solution of the salts. The remainder of the concentrated liquid can be added to the pressed admixture before or after drying to further increase the dry-solids content.

Abstract: A process for extracting xylitol from the end syrups of the xylitol crystallization by subjecting the end syrup to chromatographic separation, whereby it will be decomposed into two or more fractions, the first fraction containing mainly the polysaccharides and polysaccharide alcohols and the subsequent fractions containing essentially the pentitols and hexitols.
