Abstract
Abstract The present disclosure relates to a wax composition for entirely or partly replacing carnauba wax or montan wax. The composition consists substantially of one or more acids and or derivatives thereof selected from the group consisting of (a) esters of phenols or aromatic, aliphatic or cycloaliphatic alcohols having at least 1 to 10 primary or secondary hydroxyl groups; (b) amides of ammonia or aliphatic, cycloaliphatic or aromatic amines having at least 1 to 15 primary or secondary amino groups; (c) salts of alkali metals or alkaline earth metals, amphoteric metals, heavy metals, of ammonium or of a compound containing a tertiary amino group. The acids are obtained by the free radical addition of 1 mole of acetic anhydride to olefins containing 20 or more carbon atoms in the presence of a trivalent manganese compound.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
206 words
A wax composition for entirely or partly replacing carnauba wax or montan wax and substantially consisting of one or more acids and/or derivatives thereof selected from the group consisting of A. ester of phenols or aromatic, aliphatic or cycloaliphatic alcohols having at least 1 to 10 primary or secondary hydroxyl groups; B. amides of aliphatic, cycloaliphatic or aromatic mono- or diamines having 1 or 2 primary or secondary amino groups; C. salts of alkali metals or alkaline earth metals, emphoeric metals, heavy metals, of ammonium or of a compound containing a tertiary amino group; characterized in that at least 40% by weight of the acid present as such, or at least 40% by weight of the acid from which the derivatives are prepared has a branched-chain structure and at least 10% by weight thereof corresponds to the formula: ##STR4## where x=0, if y=2 or x=2, if y=0 R=CH 3 (CH 2 ) n , where n represents an integer from 17 to 42; b is 0 or 1, where, if b=0, Q represents a hydrogen atom, and if b=1, Q represents a CH 2 -group, and a=0 or 1, where if a=0, Z represents a hydrogen atom, and if a=1, Z represents a CH 2 -group.
Claim 2
Dependent Claim
206 words
A wax composition for entirely or partly replacing carnauba wax or montan wax and substantially consisting of one or more acids and/or derivatives thereof selected from the group consisting of A. ester of phenols or aromatic, aliphatic or cycloaliphatic alcohols having at least 1 to 10 primary or secondary hydroxyl groups; B. amides of aliphatic, cycloaliphatic or aromatic mono- or diamines having 1 or 2 primary or secondary amino groups; C. salts of alkali metals or alkaline earth metals, emphoeric metals, heavy metals, of ammonium or of a compound containing a tertiary amino group; characterized in that at least 40% by weight of the acid present as such, or at least 40% by weight of the acid from which the derivatives are prepared has a branched-chain structure and at least 10% by weight thereof corresponds to the formula: ##STR4## where x=0, if y=2 or x=2, if y=0 R=CH 3 (CH 2 ) n , where n represents an integer from 17 to 42; b is 0 or 1, where, if b=0, Q represents a hydrogen atom, and if b=1, Q represents a CH 2 -group, and a=0 or 1, where if a=0, Z represents a hydrogen atom, and if a=1, Z represents a CH 2 -group.
Claim 3
Dependent Claim
42 words
A wax composition according to claim 1 characterized in that a portion of the branched-chain acids, or a portion of the branched-acids from which the derivatives are prepared corresponds to the formula: ##STR5## where R has the meaning given in claim 1.
Claim 4
Dependent Claim
119 words
A wax composition according to the claims 1 or 2, characterized in that besides the branched-chain acids or derivatives thereof having the formulae given for these acids in claims 1 or 2 there is present an amount of 40 to 60 percent by weight of linear aliphatic monocarboxylic acids or derivatives thereof, with the acid having the formula RCH 2 CH 2 CH 2 COOH, where R has the meaning given in claim 1 and about 30 to 40 percent by weight of γ-branched carboxylic acids or derivatives thereof, with the acid having the formula: ##STR6## where R 1 and R 2 represent linear alkyl groups which together have the same number of carbon atoms as the group R.
