Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
118 words
A PROCESS OF PRODUCING A UNSYMMETRICAL HYDROXY ETHER WHICH COMPRISES REACTING AN ETHYLENIC COMPOUND, WHEREIN THE VALENCIES OF THE ETHYLENICALLY DOUBLY BONDED CARBON ATOMS ARE EACH TAKEN UP BY A MEMBER OF THE GROUP CONSISTING OF THE HYDROGEN AND CARBON ATOMS, WITH AN ALCOHOL HAVING AT LEAST ONE HYDROGEN ATOM DIRECTLY AT TACHED TO THE CARBINOL CARBON ATOM AND WITH HYDROGEN PEROXIDE UNDER THE CATALYTIC INFLUENCE OF NOT MORE THAN 0.075 MOLE PER MOLE OF HYDROGEN PEROXIDE EMPLOYED OF A STRONG ACID WHICH HAS AN IONIZATION CONSTANT FOR THE FIRST HYDROGEN GREATER THAN 1.86X10-5 AT 25*C. AND REACTS WITH HYDROGEN PEROXIDE TO FORM A PERACID, HE MOLE RATIO OF SAID ALCOHOL TO HYDROGEN PEROXIDE BEING AT LEAST 10:1.
Claim 2
Dependent Claim
