PRODUCTION OF ALPHA-CHLORO-ALPHA-OXIMINO-4-HYDROXYACETOPHENONE |
摘要 |
.alpha.-chloro-.alpha.-oximino-4-hydroxyacetophenone is prepared by reacting 4-hydroxyacetophenone with an alkyl nitrite and hydrogen chloride wherein the amount of hydrogen chloride is carefully controlled to limit the amount thereof to about 0.1 to 6 moles of hydrogen chloride per mole of 4-hydroxyacetophenone until at least one equivalent of the alkyl nitrite is reacted. Subsequent to the reaction of the one equivalent of alkyl nitrite, at least 1 mole of hydrogen chloride per mole of initially charged 4-hydroxyacetophenone is added to the reaction medium.
