Sugar alcohol mixtures are used as antimicrobially active compounds.

Compositions for common colds

The invention relates to a method for the preparation of rhamnose from rhamnolipids, for which an acidic emulsion of the rhamnolipid is hydrolyzed at 100.degree. to 200.degree. and subsequently cooled, the aqueous phase of the resulting hydrolysate is separated from the lipid phase, its pH is raised by the addition of a basic compound, any precipitate formed is removed, the remaining solution is concentrated and either processed further directly or chromatographed on ion exchange resin, rhamnose-containing fractions being obtained as eluate, which are processed further as such or worked up into crystalline rhamnose monohydrate.

The invention relates to a process for the preparation of N-acyl derivatives of 5-aminolevulinic acid of general formula R-CO-NH-CH.sub.2 -CO-CH.sub.2 -CH.sub.2 -COOH, in which R stands for methyl, ethyl, propyl, isopropyl, butyl, phenyl, benzyl, furyl or furfuryl, as well as the hydrochloride of the free acid by acid hydrolysis, characterized in that the 5-hydroxymethyl furfural is condensed with a nitrile in acid solution and the N-acyl-aminomethyl furfural compound obtained is converted by photooxidation into a N-acyl-5-aminomethyl-5-hydroxydihydro-2,5-furan-2-one and the latter is reduced with zinc in acetic acid under ultrasonic treatment to N-acyl-5-aminolevulinic acid and by acid hydrolysis the 5-aminolevulinic hydrochloride is obtained.

Process for the preparation of N-acyl derivatives of 5-aminolevulinic

A cycloadduct of the formula ##STR1## is prepared by reacting 2,2'-(2,5-furandiyldimethylidine)bis-propanedinitrile with 8-methoxypheptafulvene to form a tetrahydroazulene intermediate and then heating a solution of the tetrahydroazulene intermediate in a boiling solvent to drive off methanol.

Dicyanoazulenyl and dicyanovinyl substituted furan

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.

Dicyanovinylsubstituted furan derivatives

Process of preparing 1,6-.beta.-D-anhydroglucopyranose (levoglucosan) in high purity is described, where the starting material with a water-content, adjusted to max. 20%, is pyrolyzed, the volatile components are condensed and this distillate is neutralized. After filtration and optional treatment with an adsorbent, the mixture is chromatographically separated over an ion-exchange resin with water as eluent. Levoglucosan containing fractions are concentrated and crystalline levoglucosan is obtained by an evaporation - and/or cooling crystallization from a supersaturated water solution.
