Translation of "Zur reaktion bringen" in English

It was also to be possible to react gaseous with liquid reactants.

Appropriately, the reacting can be effected by adding an aqueous formaldehyde solution.

Herein, the reaction is carried out in the presence of at least one secondary amine.

In particular, hydrogen donors of this type are suitable for reacting terminal double bonds.

In principle, it should also be possible to react cyclopentene directly with hydrogen bromide.

Reaction of remaining hydroxyl groups with carboxylic acids, lactones, anhydrides and/or isocyanates.

In order to bring ketones to reaction it may be necessary to apply high pressure.

It is also possible for two or more alkylene oxides together to be reacted with carbon dioxide.

It is likewise possible for two components to be combined with one another and reacted with one another.

Either inorganic or organic acids can be reacted with chitosan in the suspension.

For example, the metal can be reacted with the anhydrous alcohol, or an alcoholate of a low molecular weight alcohol can be reacted with a high molecular weight alcohol, or a double reaction of an alkali metal alcoholate and an anhydrous metal halide can be carried out.

It is more advantageous, however, to make up the solid polyisocyanate into a paste with the liquid polyol component and then bring about the reaction with blowing agent and epoxide.

Unsaturated copolymerizable groups may be readily introduced into the TDI residue slag powders by the modification reactions described above. For example, the free NCO-groups of the residue may be reacted with an unsaturated alcohol (for example, allyl alcohol or acrylic acid esters containing hydroxyl groups) or with an unsaturated carboxylic acid (for example, acrylic acid, methacrylic acid, maleic acid or fumaric acid).

In accordance with the present invention, it was surprisingly found that a-olefins and a?-diolefins can be reacted with metallic lithium in the presence of appropriate catalysts, and the reaction products include pure and stereo epecific organolithium compounds and lithium hydride.

Furthermore, it is possible to react compounds (V) (in which b=1) and orthophosphoric acid and the alcohol (I) in the abovementioned molar ratio.

However, solutions in which the amount of propionic acid is less than that of perpropionic acid are in general reacted with the cyclohexanone.

It is certainly possible to react not only one but two or three different olefins with chlorosulfonyl isocyanate.

It is also possible to react the finished component (a2) directly with the partially blocked polyisocyanate.

Alternatively, the dispersion may be directly reacted with the polyol and epoxide or oxetane and the conventional additives by the one-shot foaming process.

It is also possible to react one, two or three moles of phenolcarboxylic acid with one mole of glycerol triglycidyl ether or triglycidyl isocyanurate or 2,4,6-tris-epoxypropyltriazine or trimethylolpropane tris-(2,3-epoxypropylhexahydrophthalate), or to carry out an addition reaction between one or two moles of phenolcarboxylic acid and, for example, bis-(2,3-epoxycyclopentyl) ether or 3,4-epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate or bis-(3,4-epoxy-6-methylcyclohexylmethyl) adipate or bis-(3,4-epoxycyclohexylmethyl) adipate.

A further beneficial effect of the present process resides in the fact that it is possible for the reactants to be used and reacted with one another in relatively high concentration; despite this, finely pulverulent products of very good dispersibility are always obtained.

For example, the bisphenols used as starting products may be reacted with triaryl or trialkyl phosphites, preferably triphenyl, trimethyl or triethyl phosphite, at temperatures in the range of from 50° to 300° C. and preferably at temperatures in the range of from 80° to 250° C., and the hydroxy compounds formed, such as phenol, methanol or ethanol, are distilled off, which in the case of high-boiling hydroxy compounds is best performed under reduced pressure.

However, it can also be advantageous to react the polyamine compound with a mixture of a monoisocyanate and a polyisocyanate.

Or a bicyclo[2.2.1]hept-2-en-6-al may be caused to react with an at least trihydric alcohol to form an acetal and at least one residual alcoholic group is esterified with (meth)acryloyl chloride, in either sequence, to yield ester-acetals of formula ##STR34## where R, R1, X, a, b, and c have the meanings previously assigned and denotes the residue of a compound containing at least (2b+c) alcoholic hydroxyl groups, after removal of (2b+c) such hydroxyl groups, such as a polyvinyl alcohol of average molecular weight 500 to 9000.

It is however also possible, for example, to follow the Tcherniak-Einhorn reaction of polybutadiene-N-methylolmaleimide and acrylamide or methacrylamide by the Michael addition reaction and then to react the phenolic groups of the resulting reaction product with an excess of polyepoxide, after which the epoxide groups remaining in the product thus obtained are reacted with a Mannich base.

It is possible, for example, to follow the Tscherniac-Einhorn reaction of acrylamide or methacrylamide with a partial reaction of the double bonds by the Michael addition reaction and then to react the phenolic groups of the resulting reaction product with an excess of polyepoxide, after which the epoxide groups remaining in the product thus obtained are reacted with the Mannich base (a1).

It is also possible first to react compounds of the formula VII with cyanuric chloride in a molar ratio of 1/1 to give compounds of the general formula ##STR21## and then to react these compounds with a diamine in a molar ratio of 2/1.

From U.S. Pat. No. Re. 29,725, it is known to mix reagents and sample in an analysis container which consists of two flexible films connected together on the edge and to bring them to reaction and, inter alia, to measure the reaction product spectrophotometrically.
