摘要:
A process for producing an N-alkyl-N-methylamine or an N-alkenyl-N-methylamine in a high yield from a higher alcohol and methylamine comprising the step of reacting a higher alcohol with methylamine in the presence of a catalyst comprising copper and another fourth period transition metal of the Periodic Table, except chromium, or a catalyst comprising copper, another fourth period transition metal of the Periodic Table, except chromium, and an element of the platinum group, at a pressure ranging from atmospheric pressure to 100 atm, at a reaction temperature ranging from 100 to 250°C, with hydrogen gas being introduced into the reaction system while water produced in the reaction is removed from the reaction system and the amount of methylamine in the gaseous mixture which contains no water formed through the reaction and is exhausted from the reaction system is regulated to be from 5 to 50% by volume.
摘要:
A method for enhancing the effectiveness of an agricultural chemical which comprises incorporating a specific enhancer into a diluted solution of the agricultural chemical. The specific enhancer is a quaternary ammonium salt or a tertiary amine or a salt thereof containing one or more carboxylic acid ester or amide groups, at least one long chain alkyl or alkenyl group and optionally also ether groups.

Provided are an internal olefin sulfonate composition which is capable of sufficiently enhancing foamability, foam dissipation property free from a slimy feeling during rinsing, and a feel after cleansing and subsequent drying, and a cleansing composition containing the same. The internal olefin sulfonate composition comprises (A) an internal olefin sulfonate having 16 carbon atoms and (B) an internal olefin sulfonate having 12 carbon atoms, in which a content mass ratio of the component (A) to the component (B), (A/B), is from 10/90 to 90/10.
