Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
207 words
A process for production of saturated alcohols of the formula: by the catalytic hydrogenation of unsaturated monoesters of the formulas: which comprises hydrogenating said unsaturated monoesters in the vapor phase with hydrogen at a temperature of from about 100°C to about 250°C at a pressure of from about 2 atmospheres to about 50 atmospheres in contact with the reduced form of a catalyst comprising the formula: Zn a Cu b X c Ni d O e wherein (a) has a value of about 30 to about 75, (b) has a value of about 35 to about 60, (c) has a value of zero to about 15, (d) has a value of about 0.3 to about 2, (e) has a value sufficient to satisfy the oxides needs of the metal atoms, and the sum of (a) plus (b) plus (c) plus (d) is equal to 100, and X is of at least one other metal atom; and wherein R is (i) an alkyl group having from 1 to about 8 carbon atoms, (ii) a cycloalkyl group having 5 or 6 ring carbon atoms, or (iii) an aryl, alkaryl or aralkyl group in which the aromatic ring is phenyl or naphthyl, and R′ is hydrogen or an R group.
Claim 2
Dependent Claim
207 words
A process for production of saturated alcohols of the formula: by the catalytic hydrogenation of unsaturated monoesters of the formulas: which comprises hydrogenating said unsaturated monoesters in the vapor phase with hydrogen at a temperature of from about 100°C to about 250°C at a pressure of from about 2 atmospheres to about 50 atmospheres in contact with the reduced form of a catalyst comprising the formula: Zn a Cu b X c Ni d O e wherein (a) has a value of about 30 to about 75, (b) has a value of about 35 to about 60, (c) has a value of zero to about 15, (d) has a value of about 0.3 to about 2, (e) has a value sufficient to satisfy the oxides needs of the metal atoms, and the sum of (a) plus (b) plus (c) plus (d) is equal to 100, and X is of at least one other metal atom; and wherein R is (i) an alkyl group having from 1 to about 8 carbon atoms, (ii) a cycloalkyl group having 5 or 6 ring carbon atoms, or (iii) an aryl, alkaryl or aralkyl group in which the aromatic ring is phenyl or naphthyl, and R′ is hydrogen or an R group.
