摘要:
The cold flow properties of fuels, in particular, diesel fuels can be improved by the addition of reaction products of amines of general formula (I) NR1R2R3 in which R1, R2, R3, independently = H, 1 to 22 C alkyl, or a 1 to 22 C hydroxylalkyl group or a 1 to 22 C aminoalkyl with fatty acids of general formula (II) R4-COOH in which R4 = branched or unbranched 7 to 25 C alkyl or alkylene group in the molar ratio (I) : (II) of 1 : 1 to 1 : 3 at a temperature of 80 to 140 °C.
摘要:
Disclosed are compositions containing trimethylolpropane ester (TMP)-ester of general formula (I), wherein R1, R2, and R3 identically or differently represent a straight-chain or branched-chain alkyl group comprising 5 to 11 C atoms. The ester has a viscosity of less than 23 mm2/s at 40 °C and an ignition point > 300 °C. The inventive compositions are used as a dielectric insulating liquid for transformers.
