Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
81 words
AN ALKOXY-SUBSTITUTED MONO-ETHYLENIC CARBONYL COMPOUND OF THE GROUP CONSISTING OF CARBOXYLIC ACIDS HAVING 9 TO 18 CARBON ATOMS IN THE ACID MOIETY AND 1 TO 5 CARBON ATOMS IN THE ALKOXY GROUP AND ALKYL ESTERS OF SAID ACIDS HAVING 1 TO 5 CARBON ATOMS IN THE ALKYL ESTERS GROUP, THE ALKOXY GROUP BEING IN ALLYL POSITION WITH RESPECT TO THE ETHYLENIC DOUBLE BOND WHICH IS SEPARATED FROM THE CARBOXYL CARBON ATOM BY A HYDROCARBON RADICAL OF 6 TO 14 CARBON ATOMS.
Claim 2
Dependent Claim
81 words

Claim 3
Dependent Claim
14 words
ALKYL 10-ALKOXY-8-HALO-8-DECENOATE WHEREIN EACH OF SAID ALKYL GROUPS CONTAINS 1 TO 4 CARBON ATOMS.
Claim 4
Dependent Claim
14 words
ALKYL 10-ALKOXY-8-HALO-8-DECENOATE WHEREIN EACH OF SAID ALKYL GROUPS CONTAINS 1 TO 4 CARBON ATOMS.
Claim 5
Independent Claim
93 words
A METHOD FOR PRODUCING A MONO-ETHYLENIC DIETHER HAVING AT LEAST ONE OF THE ETHER GROUPS IN ALLYLIC POSITION WITH RESPECT TO THE ETHYLENIC DOUBLE BOND WHICH COMPRISES GENERATING AN ALKOXY FREE RADICAL BY DECOMPOSING AN ALKYL HYDROPEROXIDE BY REDOX REACTION WITH FERROUS ION IN THE PRESENCE OF A CONJUGATED DIENE, AND OF A SOLUBILIZING ALCOHOL SOLVENT FOR THE REACTANTS CONTAINING BETWEEN ABOUT 0.01 AND ABOUT 0.6 EQUIVALENTS OF CUPRIC ION PER MOLE OF ALKYL HYDROPEROXIDE WHEREBY COMBINATION OF SAID FREE RADICAL AND ALCOHOL SOLVENT WITH THE DIENE TAKES PLACE IN EQUAL MOLE PROPORTIONS.
