摘要:
AbstractIn this paper, the results of fractionation of polyalkyl benzene residues from monoalkyl benzene production, using a molecular evaporator to obtain fractions which are usable as lubrication oils for refrigeration compressors with a non‐polar refrigerant, are presented. Two of the distillion fractions pre‐pared correspond to international viscosity classes I S 0 VG 22 and 46. Their yields of 45 and 15% respectively from the original residues are economically interesting and they are of a higher quality than the previously used mineral oil based lubricants. The polyalkyl benzenes have improved properties, such as viscosity index, flash point temperature, and pour point. The lower thermo‐oxidative stability of the fractions is compensated for formulations with appropriate antioxi
