Abstract (en)

[origin: WO2010000760A2] The present invention provides a gasoline composition comprising: (i) base gasoline; and (ii) a composition comprising component A and at least one component selected from categories (a) and (b) below: (a) component B, and (b) one component selected from components C, D and E, wherein: component A is an ester or mixture of esters having formula (I): R1C(O)-O-R2 wherein R1 is selected from a C1-6 alkyl group and R2 is selected from a C1-4 alkyl group and wherein the total number of carbon atoms in R1 and R2 is in the range of from 5-9, with the proviso that component A has a boiling point or boiling point range within the temperature range of from 90 to 200 0C; component B is ethanol; component C is a compound of formula (II) or formula (III). wherein the R3, R4, R5 and R6 groups are independently selected from hydrogen and C1-6 hydrocarbyl groups, with the proviso that component C has a boiling point or boiling point range of at most 110 0C; component D is butanol; and component E is an ether of the general formula (IV): R7-O-C(Me)3 wherein R7 is selected from methyl, ethyl or mixtures thereof, wherein the concentration of the components in the composition is calculated using the following equation (equation I ). wherein : n = 1 is component B, n = 2 is component A, n = 3 is any one of components C, D or E, Vfn is the volume fraction of the component n = 1, 2 or 3 in the composition comprising component A and at least one component selected from components B, C, D and E, E70 n is the blending E70 value of the component represented by n, E1OOn is the blending E1OO value of the component represented by n, E70base is in the range of from 10 to 55 %vol., and ElOObase is in the range of from 35 to 75 %vol..
