Abstract: A liquid mixture having a cetane number higher than 40, comprising a typical diesel gas oil cut having a boiling point ranging from 150 to 380null C., and a density ranging from 0.76 and 0.935 g/ml at 15 null C.; and one or more compounds selected from dialkyl-polyformals represented by the formula RO(CH2O)mR, wherein R is a CnH2nnull1 alkyl chain, m is an integer equal to or greater than 2 and less than or equal to 6, n is an integer ranging from 1 to 10, wherein the concentration of these dialkyl-polyformals in the gas oil ranges from 1 to 20%; and a process for production of dialkyl-polyformals using sulfonic acid-based catalysts.
