    摘要: Selective production of a dialkanolamine is attained by controlling the volume preceding the entrance to a catalyst bed and the temperature prevailing under respectively fixed levels subsequent to the mixture of an alkylene oxide thereby repressing a reaction occurring in the absence of a catalyst and curbing the formation of trialkanolamine.
    The reactant fluid is prevented from generating a channeling by disposing an exportable structure in a reactor thereby creating the state of a false shell-and-tube type reactor.
    The reaction is initiated with the inlet temperature set at a higher level than the prescribed level and the alkylene oxide concentration set at a lower level than the prescribed level and thereafter the inlet temperature and the alkylene oxide concentration are gradually changed toward the respectively prescribed levels.

    摘要: A method for scavenging mercaptans in hydrocarbon fluid is disclosed. According to the method, an effective mercaptan-scavenging amount of an aqueous scavenging composition is added to the fluid. The composition comprises a quaternary ammonium hydroxide of the formula R¹R²R³R⁴NOH. R¹ and R² are, independently, alkyl groups of from one to about eighteen carbon atoms, aryl groups of from six to about eighteen carbon atoms or alkylaryl groups of from seven to about eighteen carbon atoms. R³ is an alkyl group of from two to about eighteen carbon atoms, an aryl group of from two to about eighteen carbon atoms or an alkylaryl group of from four to about eighteen carbon atoms. R² and R³ may be joined to form a heterocyclic ring including the N and optionally an oxygen atom. R⁴ is -(CH₂CH₂O)nH, wherein n is an integer from one to about eighteen, or -CHR⁵CHR⁶Y, wherein R⁵ and R⁶ are, independently, hydrogen, alkyl groups of from one to about eighteen carbon atoms, aryl groups of from six to about eighteen carbon atoms or alkylaryl groups of from seven to about eighteen carbon atoms. Y is a non-acidic group. A method of preparing certain such quaternary ammonium hydroxides is also disclosed.
