Organic reactions involving acetals in the presence of mixed anionic cationic ion exchange resins as catalysts

Claim 1

A PROCESS WHICH COMPRISES REACTING AN ACETAL AND AN ORGANIC COMPOUND HAVING AN ACIDIC HYDROGEN ON A CARBON ATOM AND YIELDING A CARBANION, WHICH COMPOUND CONTAINS THE GROUP =CH- AND IS CAPABLE OF REACTING AT THIS GROUP WITH AN ALKALI METAL ALCOHOLATE TO REPLACE THE HYDROGEN THEREOF WITH ALKALI METAL, SAID REACTION BEING EFFECTED IN THE PRESENCE OF WATER AND OF A MIXTURE OF A BASIC ANION-EXCHANGE RESIN AND A STRONGLY ACIDIC CATION EXCHANGER, AND SEPARATING AN ALCOHOL AND THE REACTION PRODUCT FROM SAID SAID ACETAL AND ORGANIC COMPOUND, SAID ACETAL HAVING THE STRUCTURE ROR''C (OR)2 WHERE THE R''S TAKEN INDIVIDUALLY REPRESENT LOWER ALKYL GROUPS AND WHEN TAKEN TOGETHER REPRESENT AN ALKYLENE GROUP OF TWO TO THREE CARBON ATOMS WHICH TOGETHER WITH THE OXYGEN, ALKYL AND CONNECTING CARBON ATOM FORMS A HETEROCYCLE, R* IS A MEMBER OF THE CLASS CONSISTING OF HYDROGEN, ALKYL GROUPS OF NOT OVER 11 CARBON ATOMS, AND ALKENYL GROUPS OF TWO TO SEVEN CARBON ATOMS, AND R'' IS A MEMBER OF THE CLASS CONSISTING OF HYDROGEN AND ALKYL GROUPS OF NOT OVER SEVEN CARBON ATOMS.
