Abstract: Aromatic mono or polycarboxylic acid glycidyl esters are obtained in good yields and high purity by transesterification of the corresponding aromatic carboxylic acid alkyl esters with glycidol in the presence of weakly toxic catalysts, namely the alkali, ammonium, and alkaline earth metal salts of pseudohalogen hydride acids with readily polarizable anions.

Abstract: There are employed water soluble low molecular weight polycondensation products produced by the condensation of acrolein and formaldehyde in a molar ratio between 1:1 and 1:10 in aqueous or aqueous-organic medium in the presence of a basic catalyst for the elimination of hydrogen sulfide and iron sulfide present in aqueous systems. The condensation reaction can also be carried out in the additional presence of water soluble monohydric or polyhydric alcohols and/or acid amides.

Abstract: Pentaerythritol is treated at a temperature of about 180.degree. to 220.degree. C. with a strongly alkaline acting material, e.g. calcium oxide. The thus treated pentaerythritol serves as a costabilizer e.g., with the salt of a polyvalent metal and a carboxylic acid, for a vinyl chloride resin, e.g. polyvinyl chloride and has outstanding properties as such.

Abstract: There is described new alkylene bismelamines and their production. They correspond to the formula ##STR1## in which o is a number from 10 to 18. Alkylene bismelamines serve as stabilizers for formaldehyde solutions and as such have an outstanding suitability and activity.

Abstract: There are employed as biocides for aqueous systems water soluble low molecular weight polycondensation products which are produced from acrolein and formaldehyde in the molar ratio between 1:1 and 1:10 in aqueous or aqueous-organic medium in the presence of a basic catalyst. The condensation reaction can also be carried out in the additional presence of water soluble mono- or polyhydric alcohols and/or acid amides.

Abstract: Pure hydroxypropyltheophylline is produced by the catalytic reaction of theophylline with glycidol in the presence of a hydroxide of a short chain alcoholate of an alkali metal or an alkali metal salt of a pseudohydrohalic acid which has a readily polarizable anion. The catalyst is suitably employed in an amount between 0.01 and 0.2 moles per mole of theophylline. The dihydroxypropyltheophylline is obtained directly in the reaction in a high purity.

Abstract: Guaiacol glycerine ether is obtained in very good yield and in very high purity by reacting glycidol with o-methyoxyphenol in the presence of an alkali hydroxide, an alkali alcoholate, an alkali cyanate or an alkali thiocyanate at 80.degree. to 150.degree. C. An especially effective purification of the crude product can be obtained by adding hydrogen peroxide, preferably prior to cooling.

Abstract: There are described new bisguanamines of the formula ##STR1## where n is a number from 10 to 20 and their production. The bisguanamines are stabilizers for formaldehyde solutions and have outstanding qualifications and action for this purpose.
