A method is provided for the continuous production of saturated aliphatic alcohols having from 2 to 5 carbon atoms by hydrating the corresponding aliphatic olefin in the presence of a sulfonated styrene-divinylbenzene copolymer catalyst having a specific surface area measured in the dry state employing the BET method of:

Trickle-type fixed-bed catalytic reactions are improved, prior to starting or resuming an on-stream period, by purging air from the catalyst bed and reaction zone by downward flow of an inert gas therethrough, flooding the purged reaction zone by flowing a liquid upwardly through the catalyst bed to cover same, then removing the liquid and instituting the on-stream period by introducing gaseous and liquid reactants at the upper end of the catalyst bed to flow downwardly therethrough.

Process for the production of film forming synthetic resins for hair fixative compositions by reacting a methylolated 5,5-dialkylhydantoin containing 1-5 carbon atoms in each alkyl group at an elevated temperature in the presence of a bifunctional acid amide and/or amine. Hair fixative compositions containing 2-10% by weight of the resin product as the major or sole resin compound.
