Abstract: Benzaldehyde derivatives of the formula in which X denotes an oxygen atom or two R O groups in which R represents a methyl or ethyl group, R represents an iso-propyl or tert-butyl group and R , in the case that X represents these two R O groups, can also denote an alkoxy group having 1 to 4 carbon atoms, and a process for the preparation of these compounds.
