ABSTRACT:
Disclosed are a process for producing a substituted phenoxyacetaldehyde oxime of the formula: ##STR1## (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined in the specification), which comprises allowing a substituted phenoxyacetaldehyde dialkylacetal of the formula: ##STR2## (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are as defined in the specification) to react with hydroxylamine; a process for producing a substituted phenoxyethylamine of the formula: ##STR3## (wherein R.sup.1, R.sup.2 and R.sup.3 are as defined in the specification), which comprises reducing a substituted phenoxyacetaldehyde oxime of the formula (II) with hydrogen in the presence of a Raney-nickel catalyst; and a substituted phenoxyacetaldehyde oxime of the formula: ##STR4## (wherein R.sup.1, R.sup.2 and R.sup.6 are as defned in the specification).
