“…Cellulosic fibers obtained by solvolysis are suitable for papermaking (Kleinert 1974;Nelson et al 1977) or conversion to glucose by enzymatic hydrolysis (Zhang et al 2013;Sun and Cheng 2002). Lignins isolated by solvolysis are usable as fuel and adhesives (Gast and Puls 1985), resin (Lora and Aziz 1985), and starting materials for several application (Espinoza-Acosta et al 2014;Moghaddam et al 2014). Thring et al (1989) isolated lignin from the spent black liquor produced during the solvolysis of poplar using ethylene glycol, with the aim of using the lignin fraction as chemical feedstocks for conversion into monomeric chemicals.…”

The acidic solvolysis of lignocellulose using a glycol solvent such as polyethylene glycol (PEG) is a promising process for separating its components and producing a valuable lignin product that can be used as thermoplastic and fusible materials. To decrease operational costs, a glycol solvent that is used as a solvolysis reagent must be recovered and reused. In the present study, PEG was recovered by the removal of water by evaporation from the supernatant after glycol lignin production by acidic solvolysis of Japanese cedar using PEG with an average molecular weight of 200 (PEG200). The recovered PEG200 worked as a solvolysis reagent and produced glycol lignin with appropriate yield. The thermomechanical analysis of glycol lignin from the fresh and recovered PEG200 systems exhibited two inflection points, which were assigned to a glass transition point (Tg) and a thermal softening point (Ts). The Ts of the glycol lignin from the recovered PEG200 system was higher than that from the fresh PEG200 system. These results suggest that the glycol lignin from the recovered PEG200 system had high thermostability as well as high thermal fusibility.

“…Lignin contributes to the recalcitrance of lignocellulosic biomass and affects enzymatic activity during biorefinery operations, therefore, it must be removed before further processing [88]. Organic solvents and ILs are two important pretreatments for delignifying lignocellulosic biomass; both have been proven beneficial for fractionating and recovering cellulose and hemicellulose, as well as lignin with useful physicochemical properties.…”

“…Ionic liquids can either dissolve the lignocellulosic biomass completely or dissolve it into individual fractions. The advantages and disadvantages of organic solvents and ILs were considered, since both are important methods to fractionate lignocellulosic biomass in their main components which can be converted into value added products [88].…”

“…ILs have been long appreciated for their physico‐chemical properties, which include low melting temperature, limited volatility or flammability and a high thermal stability. The viscosity and the dissolution properties of ILs can be modified by mixing with water, different organic solvents or even different ILs resulting in a change of selectivity towards the extraction of different biomass components 50. The extraction ability of ILs can be additionally influenced by using a catalyst.…”
