Abstract (en)
[origin: EP0918084A2] Fatty acid derivatives of specified formula are used as additives in conveyor lubricants. The fatty acid derivatives are of formula: RC(O)X(CH2CH2O)nR' (where, R = 6-30 C fatty acid residue, which can have 1-3 carbon-carbon double bonds that can be epoxidised and subsequently converted with compounds of formula: R1O(CH2CH2O)x (where, R1 = H or 1-18 C alkyl and x = 0-50; X = O or NR''; R'' = H, (CH2CH2O)pR' or optionally 1-20 C alkyl interrupted by 1-5 O atoms or NH(CH2)mNR'''; R''' = H or (CH2CH2O)pR'; m = 1-6; p = 1-20; R' = H, 1-10 C alkyl, or (O)CR; and n = 1-20). An Independent claim is also included for a conveyor lubricant containing (in wt.%): (a1) 1-30 compound of formula (I) (A1); (b1) 0-30 complex former (B1); (c1) 1-20 fatty alcohol ethoxylate (C1); (d1) 0-25 fatty acids (D1); (e1) 0-25 further additives (E1); and (f1) an amount of amine (F1) sufficient to give the lubricant an alkaline pH; or (a2) 0.5-15 compound of formula (A2); (b2) 0.5-15 ether carboxylic acid (B2); (c2) 0.5-20 fatty alcohol ethoxylate (C2); (d2) 0-25 fatty amine (D2); (e2) 0-10 further additives (E2); and (f2) an amount of carboxylic acids (F2) sufficient to protonate the fatty amines (D2).
