    Abstract: Mezclas de monoésteres de ácidos carboxílicos di o tribásicos de fórmulas I y II, (MOOC)a-R1-CO-OR2 (I) [(MOOC)a-R1-CO-O]2R3 (II) en las que a significa las cifras 1 o 2, M representa hidrógeno o un equivalente metálico y R1 significa un resto de hidrocarburo alifático o cicloalifático, di o trivalente, saturado o mono o diinsaturado, con de 2 a 6 átomos de C, que puede estar sustituido por un grupo de ácido sulfónico, o un resto de hidrocarburo aromático, di o trivalente, con 6 átomos de C, R2 alquilo predominantemente ramificado, opcionalmente sustituido por hidroxilo, alcoxilo, alquilcarboniloxilo o alcoxicarbonilo, con de 9 a 51 átomos de C y R3 alcanodiilo con de 10 a 30 átomos de C, con éteres y ésteres sin grupos OH con de 18 a 45 átomos de C y opcionalmente alcanoles de fórmula R2OH y alcanodioles de fórmula R3(OH)2, de modo que, con respecto a la suma SUG de los pesos de los éteres sin grupos OH, de ésteres sin grupos OH, alcanoles, alcanodioles y grupos ¿OR2 y (-O)2R3 contenidos en la mezcla, la proporción de los grupos ¿OR2 es de hasta el 85%, la proporción de los grupos (-O)2R3 hasta del 16% y la proporción de los éteres y ésteres sin grupos OH hasta del 45%.

    Abstract: Mixtures of monoesters of di- or tri-basic carboxylic acids with OH group free 18-45 C ethers and esters and optionally alkanols and alkanediols contain up to 85 wt.% OR groups, up to 16 wt.% CO2R groups and up to 45 % OH-free ether and ester groups (w.r.t. to the total weight of OH-free ether, OH-free ester, alkanols, alkanediols, OR and CO2R groups). Mixtures of monoesters of di- or tri-basic carboxylic acids of formula (MOOC)a-R -COOR (1) and ((MOOC)a-R1-COO)2R (2) with OH group free 18-45 C ethers and esters and optionally alkanols of formula R OH and alkanediols of formula R (OH)2 contain up to 85 wt.% -OR groups, up to 16 wt.% (-O)2R groups and up to 45% OH-free ether and ester groups (w.r.t.to the total weight of OH-free ether, OH-free ester, alkanols, alkanediols, OR and CO2R groups). a = 1 or 2; M = H or a metal equivalent; R = 2-6C divalent or trivalent, saturated or mono- or bi-unsaturated aliphatic or cycloaliphatic, optionally substituted by a sulfonic acid group or is a di- or trivalent 6C aromatic hydrocarbon; R = branched optionally 9-51C alkyl, optionally substituted by alkoxy, alkylcarbonyloxy or alkoxycarbonyl; R = 10-30C alkanediyl. Independent claims are included for: (i) a process for the production of a mixture of monoesters of formula (1) and (2) by reaction of an internal anhydride of di- or tri-basic carboxylic acids with alkanols of average and/or greater chain length whereby (A) internal anhydrides of formula (3) and a mixture of alcohols of formula R OH, alkanediols of formula (HO)2R and OH group free 18-45C ethers and esters and (B) in case where R exhibits a sulfo group, for step (A) an anhydride of formula (3) is added whereby R is at least mono-unsaturated and the resulting mono-ester mixture, optionally after at least partial neutralization of free carboxyl groups with a water soluble sulfite, hydrogensulfite or disulfite by addition of the sulfite and/or hydrogen sulfite to the double bond of R with formation of the desired sulfonic acid; and (ii) a composition containing a mixture of mono-esters and lubricants and/or hydrophobic substances for the greasing and/or hydrophobic treatment of leather.
