摘要:
Suggested are degreasing compositions comprising at least one dialkyl amide according to general formula (I)
R 1 CO-NR 2 R 3 (I)
in which R 1 CO stands for a linear or branched, saturated or unsaturated, aliphatic or aromatic, optionally hydroxysubstituted acyl radical having 2 to 56 carbon atoms, and R 2 and R 3 represent independently from each other alkyl radicals having 1 to 6 carbon atoms.
摘要:
Suggested are degreasing compositions comprising at least one glycerol acetal or ketal according to general formula (Ia) or (Ib)
in which R 1 stands for hydrogen or an hydroxyl group, and R 2 and R 3 independently from each other mean hydrogen, an hydrocarbon radical having 1 to 22 carbon atoms, and 0 or up to 3 double bonds - optionally substituted by an amine, hydroxyl, phenyl or hydroxyphenyl group.
摘要:
Suggested are biocide compositions, comprising (a) 2-Furoic and/or Tetrahydro-2-furoic acid amides; (b) Biocides and optionally (c) Oil components or co-solvents and/or (d) Emulsifiers. The compositions show high solubility for biocides and improved emulsification properties.
摘要:
Suggested is a process for making acyclovir pro-drugs by esterification of 9(2-hydroxyethyoxymethyl)-guanosine (Acyclovir) with an acylation agent, which is characterised in that the reaction is conducted in the presence of a solvent which is chosen from the group of dialkyl amides.
