Abstract: A process for the acetylation of the sterically non- hindered amino group in diamines (I) with a sterically hindered amino group and another non-hindered amino group comprises reacting the diamine with ketene. Preferably the reaction is carried out at -30 to 65 degrees C in an aprotic solvent, preferably THF. The sterically hindered amine function is part of a heterocycle. Preferred (I) is TAD.

Abstract: Polyalkylamine derivatives of formula ZCH2NH2-nHn (I) are new. (where, n = 0 or 1; z = polyalkyl residue of molecular weight 150-40000; Y = residue of formula (IIa) or (IIb); R, R1 and R2 = H, optionally substituted alk(en)yl, alkinyl, and optionally substituted cycloalkyl, aryl(alkyl) having heteroatom(s); A = alkylene imine residues of formula (III); m = 0-10; Alk = optionally substituted alkylene; R3 = H, alk(en)yl, alkinyl, or aryl or when Y is a residue of formula (IIa) keto residue of formula (IVa); in (IVa): R = as above or when Y = group of formula (IIb), is a cyano residue of formula (IVb) (where, R1 and R2 = as above) or when n = 0 one of the residues Y is optionally a polyoxyalkylene residue (V) (where, q = 1-30; Alk = as above; and E = H or 1-6C alkyl). Preparation of the derivatives is also claimed. Also claimed are lubricant and fuel compositions containing the above derivatives.

Abstract: The invention relates to carbonyldiimidazoles having the general formulae (Ia), (Ib), (Ic), or their mixtures. In these formulae, R stands for a C1-4-alkyl radical and R is hydrogen or a methyl radical. The invention also relates to tert-butyl esters derived from these carbonyldiimidazoles.

Abstract: A process for reducing the dimerisation of piperidines of formula (I), in which R -R = 1-6C alkyl, or R /R or R /R together may form a CH2 chain with 2-5 C atoms. The process comprises adding to (I) 0.001-0.2 wt% of a reducing agent of formula MXH4-mYm (III), in which M = alkali metal, NR4 (with R = 1-4C alkyl) or one equivalent of alkaline earth metal or zinc; X = boron or aluminium; Y = H or CN; m = 0 or 1. Also claimed is a mixture containing (A) a piperidine of formula (I), (B) 1-1000 ppm of a compound of formula (II) and (C) 0.001-0.2 wt% reducing agent (III).
