摘要:
A mixture of sulfates is made by dimerizing one or more even numbered alpha olefins to produce one or more vinylidenes; hydroformylating the vinylidene(s) to produce a mixture of alcohols; and sulfating the mixture of alcohols to form alcohol sulfates. The sulfates are useful in laundry detergents and other surfactants.
摘要:
The present invention relates to a process for the preparation of the mono sodium salt of the derivative 3,5-diiodo-O-[3-iodo-4-(sulphooxy)phenyl]-L- tyrosine (T3S) by starting from the corresponding phenolic compound, in the presence of chlorosulfonic acid and dimethylacetamide as a solvent. The so obtained T3S compound may conveniently be isolated in a pure form as a solid in good yields. The present invention further relates to the process for T3S preparation, wherein the starting reagent is T2 and further comprising the formulation of such compound in tablets. Furthermore, the invention discloses non-radioactive immunoassays based on T3S derivatives.

摘要:
The invention provides methods for isolating and enhancing the levels of jasmonates from cacao plant sources. In a preferred embodiment, jasmonic acid and 12-hydroxy jasmonate sulfate are detected in various cocoa products, and the levels of these compounds can be manipulated to increase the beneficial health effects of a food product made with the cocoa products The invention includes methods to prepare edible products containing cocoa jasmonates.
摘要:
A process for the preparation of alkoxysulfates from organic compounds containing one or more nucleophilic groups by reacting said organic compound, in a water- miscible solvent selected from the group consisting of sulfur-containing solvents such as dirnethylsulfoxide (DMSO) or sulfolane, or polar solvents such as tetrahydrofuran (THF), dimethylformamide (DMF), dimethylacetamide (DMA) and hexamethylphosphoric triamide (HMPT), with an alkylene sulfate, in a non-water-miscible solvent selected from the group consisting of chlorinated solvents such as methylene chloride, chloroform, carbon tetrachloride, trichloroethane or chlorinated aromatics, such as chlorobenzene or dichlorobenzene, and non-chlorinated aromatics, such as toluene or xylenes, in the presence of a base selected from the group consisting of hydroxides, carbonates and hydrogen carbonates of alkali metals or alkaline earth metals.
摘要:
A method and a device for the sulfonation or the sulfation of organic liquid raw materials with an S0 3 /air mixture and other reaction gases in order to perform rapid, highly exothermic gas-liquid reactions in conventional thin-layer falling-film reactors are disclosed. The introduction of the S0 3 /air mixture occurs through several feed locations, which are located within (along) the reaction tube or reaction tubes or in the annular gap of annular-gap falling-film reactors. High peak temperatures, undesirable byproducts, worsening of the color and local oversulfation or oversulfonation, which leads to side reactions, are largely avoided.
摘要:
The present invention relates to a novel process for the preparation of compounds of the formula (I) by mixing in a first step amino alcohols of the formula (II) with sulfuric acid to yield the salt, by then reacting them in a second step in a drying device to give sulfuric acid esters of the general formula (III) and by reacting these sulfuric acid esters in a third step with mercaptans or salts thereof of the general formula (IV): RSM in each formula, where applicable, R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R, n and M have the meanings given in the description, in the presence of a diluent and in the presence of a base.
