Changes of Sound Absorption Capability of Wood by Organosolv Pretreatment [PDF]
Journal of the Korean Wood Science and Technology, 2012 유기용매 전처리에 의한 목재 횡단면의 흡음성능과 구조적 특징의 변화를 관찰하고자 낙엽송과 백합나무로부터 원반형 시험편을 채취하였다. 탈 섬유소처리를 한 후 처리목재의 구조적 특징 변화를 관찰하고, 전달함수법을 이용하여 섬유방향 흡음율을 측정하여 이를 무처리 시의 결과와 비교하였다. 측정주파수범위(50∼6,400 Hz)에서 유기용매 전처리 시험편이 무처리 시험편보다 높은 흡음율을 나타내었으며, 특히 2∼4 kHz의 주파수영역에서는 90% 정도 높은 흡음율을 나타내었다. 70∼120°C에서 유기용매 전처리한 목재는 무처리 목재와 비교하여 1.0% 미만의 중량 감소율을 보였고, 현미경에 의해 해부학적 구조 변화를 관찰할 수 있었다.

Silica extraction from organosolv pretreated wheat straw
BioResources, 2022 The silica contained in biomass is generally recovered from the ashes after combustion. In this study, the main objective was the recovery of silica from wheat straw, without degrading the other biomass components. To achieve this goal, the wheat straw was first pre-treated by an acidic organosolv process to separate it into its three major components:

Organosolv Fractionation of Birch Sawdust: Establishing a Lignin-First Biorefinery
Molecules, 2021 The use of residual biomass for bioconversions makes it possible to decrease the output of fossil-based chemicals and pursue a greener economy. While the use of lignocellulosic material as sustainable feedstock has been tried at pilot scale, industrial ...

Integrated biorefinery for cellulosic ethanol and spherical nanolignin production from coconut waste
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Green coconut waste was subjected to different fractionation methods to obtain integrated lignin nanoparticles and cellulosic ethanol. Pretreatment with gradual addition of dilute sulfuric acid provided a higher structural hemicellulose precursor yield (68.2%).

ChemSusChem, Volume 18, Issue 6, March 15, 2025.Novel organic solvents with an unmodified carbohydrate core were synthesised both from D‐xylose and directly from biomass and were successfully used as reaction media for lipase biocatalysts to synthesise aliphatic and aromatic polyesters. Abstract The use of organic solvents in academic research and industry applications is facing increasing ...
