Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
A process for producing C 3 -C 20 aliphatic alcohols by catalytically reacting carbon monoxide, hydrogen, and acetylene, all being dissolved in a liquid medium selected from the group consisting of a fraction of saturated aliphatic C 10 -C 18 alcohols a fraction of paraffin C 12 -C 20 hydrocarbons, and a mixture of both said fractions, said reagents being reacted on a catalyst containing 92 to 95% by weight of Fe 3 0 4 , 0.5 to 2% by weight of an alkaline promoter selected from the group consisting of K 2 O and Na 2 O, 3 to 7.5% by weight of structural promoters selected from the group of metal oxides consisting of V 2 O 5 , Al 2 0 3 , SiO 2 at a temperature ranging from 170° to 220° C under a pressure of from 20 to 200 atm.
Claim 2
Dependent Claim
145 words
A process for producing C 3 -C 20 aliphatic alcohols by catalytically reacting carbon monoxide, hydrogen, and acetylene, all being dissolved in a liquid medium selected from the group consisting of a fraction of saturated aliphatic C 10 -C 18 alcohols a fraction of paraffin C 12 -C 20 hydrocarbons, and a mixture of both said fractions, said reagents being reacted on a catalyst containing 92 to 95% by weight of Fe 3 0 4 , 0.5 to 2% by weight of an alkaline promoter selected from the group consisting of K 2 O and Na 2 O, 3 to 7.5% by weight of structural promoters selected from the group of metal oxides consisting of V 2 O 5 , Al 2 0 3 , SiO 2 at a temperature ranging from 170° to 220° C under a pressure of from 20 to 200 atm.
Claim 3
Dependent Claim
19 words
A process as claimed in claim 1, wherein said liquid medium contains 10 to 50% by weight of N-methylpyrrolidone.
Claim 4
Dependent Claim
34 words
A process as claimed in claim 1, wherein the synthesis is conducted under a pressure of from 50 to 150 atm and at a temperature within the range of from 190° to 200° C.
Claim 5
Dependent Claim
48 words
A process as claimed in claim 1, wherein dissolution of the gaseous reagents is performed in the liquid medium preliminarily outside the catalyst zone and the resulting solution is continuously passed through the catalyst bed at an hourly space velocity of from 500 to 10,000 hr -1 .
Claim 6
Dependent Claim
26 words
A process as claimed in claim 1, wherein dissolution of the starting gaseous reagents is performed in a moving liquid medium directly in the catalyst zone.
Claim 7
Dependent Claim
49 words
A process as claimed in claim 1, wherein the content of the structural promoters in the catalyst is: 0.5 to 1.5% by weight of V 2 0 5 , 2.2 to 5.3% by weight of Al 2 O 3 , 0.3 to 0.7% by weight of SiO 2 .
