    摘要： The invention relates to a process for the production of esterquats in which triglycerides are transesterified with alkanolamines and the resulting fatty acid alkanolamine esters are subsequently quaternized with alkyl halides or dialkyl sulfates in the presence of solvents, characterized in that glycerol released during the transesterification is continuously removed from the reaction equilibrium.

    摘要： Disclosed is the method of determining the effectiveness of an agent for the relief of elevation of the blood pressure, comprising the steps of a) administering to a susceptible subject a quantity of a trigger substance reproducibly effective in producing within a period of six hours a perceptible increase in blood pressure lasting for at least twenty-four hours in the absence of treatment, b) administering to said subject having received said quantity of trigger substance a predetermined quantity of the agent whose effectiveness is to be determined, c) measuring the duration of said elevation of blood pressure upon administering said agent, and d) comparing the duration of said elevation with and without the administration of said agent. Also disclosed are effective quantities of certain nutrient substances which can reproducibly relieve elevated blood pressure produced in a susceptible subject by the administration of a trigger substance.

    摘要： Carboxylate protective groups, a process for their preparation, their coupling to a funcitonal group, and their useCarboxylates of polar, hydrophilic alcohols of the formula ##STR1## in which R is an unbranched or branched organic radical which contains, as polar members between aliphatic or araliphatic hydrocarbon bridges, ether oxygens, amine nitrogen groups or a mixture of ether and amine groups which can be incorporated into a cyclic structure, where the total length does not exceed 20 members and where, in the case of polyethylene glycol [(CH.sub.2 --CH.sub.2 --O).sub.n ], n indicates the number of the members and is defined as any integer, andR' is an aliphatic or araliphatic radical which has at least one functional group,are suitable as protective groups since they can be introduced selectively into functional groups of organic compounds and eliminated specifically by lipases.
