Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
98 words
A PROCESS WHICH COMPRISES HEATING CRUDE ESTERS OF FATTY ACIDS HAVING FROM 8 TO 40 CAROBON ATOMS PER MOLECULE WITH A MINERAL ACID UNDER ESSENTIALLY REFLUX CONDITIONS IN THE PRESENCE OF A MONOHYDRIC ALCOHOL AND DISSOLVED IN AN INERT ORGANIC LIQUID SELECTED FROM THE GROUP CONSISTING OF HYDROCARBONS, ETHERS, AND EXCESS ALCOHOL, FOR A PERIOD SUFFICIENT TO GENERATE MORE THAN THE THEORETICAL QUANTITY OF WATER BASED UPON ESTERIFICATION OF THE FREE FATTY ACIDS AND THE MOISTURE CONTENT OF THE STARTING MATERIALS, AND SEPARATING AT LEAST ABOUT 1.05 THEORIES OF SAID WATER FROM THE REACTION MIXTURE DURING SAID HEATING.
Claim 2
Dependent Claim

A PROCESS WHICH COMPRISES HEATING CRUDE ESTERS OF FATTY ACIDS HAVING FROM 8 TO 40 CAROBON ATOMS PER MOLECULE WITH A MINERAL ACID UNDER ESSENTIALLY REFLUX CONDITIONS IN THE PRESENCE OF A MONOHYDRIC ALCOHOL AND DISSOLVED IN AN INERT ORGANIC LIQUID SELECTED FROM THE GROUP CONSISTING OF HYDROCARBONS, ETHERS, AND EXCESS ALCOHOL, FOR A PERIOD SUFFICIENT TO GENERATE MORE THAN THE THEORETICAL QUANTITY OF WATER BASED UPON ESTERIFICATION OF THE FREE FATTY ACIDS AND THE MOISTURE CONTENT OF THE STARTING MATERIALS, AND SEPARATING AT LEAST ABOUT 1.05 THEORIES OF SAID WATER FROM THE REACTION MIXTURE DURING SAID HEATING.
Claim 3
Dependent Claim
114 words
AN IMPROVED PROCESS FOR THE PRODUCTION OF HIGH MOLECULAR WEIGHT ALCOHOLS FROM CRUDE ESTERS OF FATTY ACIDS HAVING BETWEEN 8 AND 40 CARBON ATOMS PER MOLECULE, COMPRISING HEATING SAID ESTERS WITH A MINERAL ACID UNDER ESSENTIALLY REFLUX CONDITIONS IN THE PRESENCE OF A MONOHYDRIC ALCOHOL AND DISSOLVED IN AN INERT ORGANIC LIQUID SELECTED FROM THE GROUP CONSISTING OF HYDROCARBONS, ETHERS, AND EXCESS ALCOHOL, AND DURING THE HEATING SEPARATING FROM THE REACTION MIXTURE THE MOISTURE IT ORGINALLY CONTAINED AND AT LEAST ABOUT 1.05 THEORIES OF ADDITIONAL WATER BASED UPON ESTER FICATION OF THE FREE FATTY ACIDS IN THE ESTER, AND SUBJECTING THE SO-TREATED ESTERS TO AH ALKALI METAL-REDUCING ALCOHOL PROCESS TO PRODUCE THE CORRESPONDING ALCOHOLS.
Claim 4
Dependent Claim
114 words
