  • Publication number: 20230265031
    Abstract: A method of purifying raw methanol obtained in chemical pulping, wherein heavy oil is admixed with the raw methanol to prevent precipitation, and the methanol mixture is distilled or evaporated to recover the methanol. The heavy oil is formed by mixing and heating raw methanol obtained from a side stream of chemical hardwood pulping with an acidic aqueous solution to vaporize low boiling point sulfurous compounds and provide acidified raw methanol. The acidified raw methanol is separated into a liquid top phase, a liquid aqueous middle phase, and a liquid bottom phase. The liquid bottom phase is extracted to obtain the heavy oil.

  • Publication number: 20210284759
    Abstract: The present disclosure provides a method of preparing a hydrogel product comprising crosslinked glycosaminoglycan molecules at a concentration Cfinal (mg/mL). The method comprising the steps of: a) crosslinking a glycosaminoglycan having a molecular weight of above 700 kDa in conditions so as to provide a glycosaminoglycan hydrogel crosslinked by amide bonds and having a Cmin (mg/mL) that is above Cfinal/2, wherein Cmin is the concentration of gel-form glycosaminoglycan in the gel when fully swollen in physiological buffer; b) subjecting the hydrogel from step a) to post-crosslinking degradation of the glycosaminoglycan backbone, thereby reducing the Cmin of the hydrogel to a value that is below Cfinal/2; and c) formulating the partially degraded hydrogel obtained from step b) to form an injectable hydrogel composition having a concentration of glycosaminoglycan molecules of Cfinal (mg/mL).
