Gas oil has a cetane number, determined according to the standard EN ISO 5165:1998, higher than or equal to 53. The diethyl carbonate is obtained through a process comprising the transesterification of at least one dialkyl carbonate, or of at least one cyclic carbonate, with bioethanol in the presence of at least one catalyst. Diethyl carbonate is obtained through a process comprising the reaction of urea with bioethanol, in the presence of at least one catalyst. Diethyl carbonate is obtained through a process comprising the oxidative carbonylation of bioethanol with carbon monoxide and oxygen, in the presence of at least one catalyst. The bioethanol is obtained from the fermentation of at least one biomass deriving from agricultural cultivations, such as corn, sorghum, barley, beetroot, sugar cane, or its mixtures. It is obtained from the fermentation of at least one lignocellulosic biomass selected from: products of crops expressly cultivated for energy use (such as Miscanthus, foxtail, goldenrod, and common cane), including scraps, residues and waste products, of the crops or of their processing; products of agricultural cultivations, forestation and silviculture, comprising wood, plants, residues and waste products of agricultural processing, of forestation and of silviculture; scraps of agro-food products intended for human nutrition or zootechnics; residues, not chemically treated, of the paper industry; waste products coming from the differentiated collection of solid urban waste (such as urban waste of a vegetable origin, paper); or its mixtures.
