Date Sep. 12, 1996A process for the preparation of an N-alkyl- or N-phenylalkyl-substituted pyrazole I by reacting the corresponding N-unsubstituted pyrazole II with an alcohol III of the formula R1-OH where R1 is the same alkyl or phenylalkyl group to be added to the unsubstituted nitrogen group -NH- of the pyrazole reactant. Both of the reactants, i.e. the pyrazole II and alcohol III compounds, are catalytically reacted in the liquid phase in a molar ratio of from 0.001:1 to 1:1, at temperatures of 50 DEG -400 DEG C. and under a subatmosheric pressure of from 0.8 bar up to a superatmospheric pressure of 250 bar. The catalyst required for this liquid phase reaction is selected as being at least one or more non-heterogeneous acid catalysts, their alkyl esters or their acid anhydrides.

Abstract: The invention relates to the use of aldoximes, ketoximes which are not derived from quinones, hydroxime acid esters, and N-acyl-hydroxylamine derivatives for stabilising ethylenically unsaturated compounds containing oxygen and/or nitrogen, such as (meth)acrylic acid (esters). Co-stabilisers, such as transition metal salts, phenols, quinones, or hydroquinones, N-oxyls, aromatic amines or phenylenediamines, urea derivatives, compounds containing phosphorus, compounds containing sulphur, and sulfonamides, can be used with the above-mentioned substances. Preferably, a gas containing oxygen, such as air, is present.
