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.

There are used as antistatic agents for thermoplastic synthetic resins compounds of the formulae ##STR1## where R and R' are saturated alkyl groups in which the sum of the carbon atoms in the two alkyl groups is 4 to 30 carbon atoms and wherein one of R and R' can be hydrogen,

Antistatic agents for thermoplastic synthetic resins

There are prepared compounds of the formulae ##STR1## where R and R.sup.1 are saturated alkyl groups in which the sum of the carbon atoms in the two alkyl groups is 4 to 30 carbon atoms and wherein one of R and R.sup.1 can be hydrogen, R.sup.2 is hydrogen, lower alkyl with one to five carbon atoms, 2-hydroxyethyl, 2-hydroxypropyl, 2,3-dihydroxypropyl, benzyl,o-,m- or p-methylbenzyl, o-,m- or p-chlorobenzyl, o-,m- or p-bromobenzyl, aminoalkyl (C.sub.2 to C.sub.6), preferably aminoalkyl (C.sub.2 and C.sub.3), alkyl (C.sub.1 to C.sub.5)-aminoalkyl (C.sub.2 to C.sub.6), 2-hydroxyethyl-aminoalkyl (C.sub.2 to C.sub.6), 2-hydroxypropyl-aminoalkyl (C.sub.2 to C.sub.6) or 2,3-dihydroxy-propyl-aminoalkyl (C.sub.2 to C.sub.6), R.sup.3 in case the compound is present as the ammonium salt is hydrogen or a lower alkyl group with 1 to 5 carbon atoms, and X- is a monovalent, inorganic or organic acid group or one equivalent of a polybasic inorganic or organic group. The compounds are useful as antistatic finishing agents for thermoplastic synthetic resins.

N-2,3-Dihydroxypropyl-N-2-hydroxyalkyl-amine and its salts

There are prepared compounds of the formula ##STR1## where R and R.sup.1 are saturated and preferably linear alkyl groups in which the sum of carbon atoms in the two alkyl groups is 4 to 30,
