Abstract: A process for the production of pyridine-2-carboxylic acid-(1-4C) alkyl ester compounds comprises acid hydrolysis of a 2-cyanopyridine derivative with an anhydrous inorganic acid or its anhydride in the presence of water and a 1-4C alcohol. An equimolar quantity of water is added before the addition of the acid or anhydride. A process for the production of pyridine-2-carboxylic acid-(1-4C) alkyl ester compounds (I) of formula (1) comprises acid hydrolysis of a 2-cyanopyridine derivative (II) of formula (2) with an anhydrous acid or its anhydride in the presence of water and a 1-4C alcohol. An equimolar quantity of water is added to the compound (II) before the addition of the acid or anhydride. R = H, 1-12C alkyl or alkoxy; and n = 0-4. Independent claims are included for: (1) a process for the production of terpyridines of formula (3) involves: (i) condensation of a pyridine-2-carboxylic acid-(1-4C)-alkyl ester (I) with acetone in an aprotic solvent in the presence of an alkali- or alkaline earth (1-4C)-alcoholate; (ii) reaction of the resulting 1,5-bis(2-pyridyl)pentan-1,3,5-trione compound of formula (4) with ammonia or ammonium salts of formula (5) with removal of the water of reaction using a 1-4C alcohol as a driving agent; and (iii) chlorination of the resulting 2,6-bis(2-pyridyl)-(1H) pyridone compound of formula (6) using POCl3 and toluene, o-xylene, m-xylene and/or p-xylene; (2) a processes for the production of the 1,5-bis(2-pyridyl)-pentan-1,3,5 trione compounds of formula (4) and 2,6-bis(2-pyridyl)-4(1H) pyridone compounds of formula (6).

Abstract: Surprisingly, it has been shown that the drawbacks of the previous state of the art, e.g. composition, purity and quality, and price variations of lanolin, can be avoided by substitution of crude, cleaned, and chemically modified wool fat and wool fat based mixtures by polyisobutene and polyisobutene derivatives as stuffing agents. A new stuffing agent for stuffing of skins and leather production including neutral and/or chemically modified native stuffing components (0-97 wt.%), one or more emulsifiers, and polyisobutene and/or polyisobutene derivatives of formula (I): R = a residue of formula (II), (III), or (IV); n = no value between 8 and 800; R = H or 2-8C alkyl, which can be substituted by one or two carboxyl or carboxylate groups, 1-6C alkoxycarbonyl with 1-6C in the alkoxy residue, alkylamino or dialkylamino-alkoxycarbonyl with a total of 1-6C in the alkylamino or dialkylamino groups, amidocarbonyl, cyan, phenyl, hydroxy, poly-lower alkoxy, lower acyloxy, or by the divalent group -O-CO-O- with which it forms a five-or six membered ring; R = R or with the exception of H, where the two R residues can be the same or different; R and R = H, OH, lower alkoxy, poly-lower alkoxy, or R or R = H and the other residue = sulfate (-OSO3H) or sulfone group (-SO3H), amino, alkylamino dialkylamino, with a total of 1-6C in the alkyamino or dialkylamino groups, or for groups of formula -O(CpH2p)COOH); p = 1-7, or their salts or 1-5C lower alkyl ester. The polymer has the formula (I), where R = a residue of formula (II) and R = H. Independent claims are included for: (1) a process for preparation of a polyisobutene stuffing composition by mixing at least one neutral and/or optionally a chemically modified, native stuffing component; and (2) a process for stuffing hides using polyisobutene directly as the stuffing material and/or a polyisobutene derivative in use singly or in combination with other stuffing materials, e.g. in the form of an aqueous emulsion.
