- the present invention relates to a chemical pretreatment process of lignocellulosic biomass employing ionic liquid consisting of dicoline phthalic salt.
- Said process comprises the step of contacting a lignocellulosic biomass with an ionic liquid consisting of dicoline phthalic salt in a 1: 1 to 1: 100 mass ratio of biomass: ionic liquid.
- Said contact step occurs for a period of time which varies from 0.4 to 48 hours and at a temperature ranging from 60 ° C to 200 Q C
- the ionic liquid is selected from the salts of dicoline phthalate, dicoline isophthalate and dicoline terephthalate.
- the ionic liquid employed is selected from dicoline isophthalate and dicoline terephthalate.
- the italic salts of dicoline described in the present invention are defined as ionic liquids since such salts have been found to be in liquid form at operating temperatures.
- the kinematic and dynamic viscosities of this salt at different temperatures less than or equal to 100 ° C are shown in Table 1 below.
- the dicoline terephthalate salt [Ch] 2 [Ter] did not melt or flowed at temperatures of 100 ° C or below.
- the definition of the operating temperature will depend on the salt employed, being certain that it must be sufficiently high to guarantee the classification of the salt as an ionic liquid.
- agitation may be employed in a range of 100 to 400 rpm. Preferably, the agitation employed is about 250 rpm.
- the process comprises a subsequent phase separation step selected from centrifugation, filtration and decantation. At this stage there is formation of a solid fraction and a liquid fraction.
- the liquid fraction comprises pretreatment liquors such as extracted lignin, free sugars, acetic as well as furfural and 5-hydroxymethylfurfural (5-HMF).
- the solid fraction contains the pre-treated lower lignin biomass along with the excess phthalic salt used.

- ethanol or a mixture of these can be used and can be carried out from 1 to 10 wash cycles.
- the lignocellulosic biomass to be employed in the pretreatment process disclosed herein can be selected from crop residues, hardwood, coniferous wood, cellulosic waste, herbaceous biomass, and municipal solid waste.

- the reaction medium was composed of 100mM sodium citrate buffer at pH 5.0 and the commercial enzyme Cellic CTec3 ® (supplied by Novozymes), added at a 4.2% loading (preparation volume / sample mass) .
- the initial pretreated bagasse content in the reaction was only 1% (w / v) and samples were taken over the 24 to 96 hour reaction period.
- the glucose concentration released by hydrolysis was increased by up to 8.1 times, relative to the glucose released by the bagasse sample that had not been pretreated with the ionic liquid. Concentrations are expressed based on the sugar mass fraction by dry pretreated biomass.
