    Abstract. We investigated the reaction behavior of milled wood lignin MWL obtained from Japanese cedar Cryptomeria japonica and Japanese beech Fagus crenata in an ionic liquid, 1-ethyl-3-methylimidazolium chloride C2mimCl.This solvent can liquefy wood. The sample was treated with C2mimCl at 120 C using an oil bath or microwave irradiation.

    Two Trichome Birefringence-Like Proteins Mediate

    Acetylation is a ubiquitous modification on cell wall polymers, which play a structural role in plant growth and stress defenses. However, the mechanisms for how crop plants accomplish cell wall polymer O -acetylation are largely unknown. Here, we report on the isolation and characterization of two trichome birefringence-like tbl mutants in rice Oryza sativa , which are affected in ...

    Milling in Seconds Accelerates Acetylation of

    2019-10-9A new sustainable synthetic method for cellulose acetate was developed by a combination of I2-catalyzed solidliquid acetylation of cellulose and a milling process reducing the crystallinity of cellulose within a few seconds. Milled low-crystalline cellulose was acetylated faster than the original cellulose with higher crystallinity. The plausible factors of acceleration were the conversion ...
