Process for preparing acylphenols, and more specifically a compound of the formula: ** (See formula) ** which comprises the decomposition of a compound selected from the group consisting of a compound of the formula: ** (See formula) ** where R is a member selected from the group consisting of lower alkyl, lower haloalkyl, cycloalkyl, ** (See formula) ** wherein X1 is, in each case, a member selected from the group consisting of hydrogen, halogen and lower alkyl, and m is an integer having a value of 1 to 5, R3 is a member selected from the group consisting of lower alkyl and, when considered together with the nitrogen atom to which it is attached, it forms a mononuclear heterocyclic group, R4 represents a hydrocarbyl radical, X represents one or more similar or non-similar radicals selected from the group consisting of halogen, lower alkyl and, when are substituted on adjacent carbon atoms of the benzene nucleus, two radicals X can be combined to form a hydrocarbylene chain containing 3 to 4 carbon atoms between their attachment points, Y ‾ represents an anion, HA is an acid selected from the group consisting of organic or inorganic acids capable of forming salts with amines, W is an integer having a value of 0 to 1 and n is an integer having a value of 1 to 4.
