DES提取木質(zhì)素步驟求助
|
||
|
Biomass-based strong adhesive based on supramolecular deep eutectic solvents pretreatment這篇文獻(xiàn)中他講的 2.2 Preparation of DES DES preparation was carried out by mixing β-cyclodextrin and L-malic acid and stirring them in an oil bath pot at 120℃ until a homogeneous and transparent liquid was obtained (65.31 g). The molar ratio of β-cyclodextrin and L-malic acid was 1:40 unless otherwise specified. 2.3 Preparation of ALDES Firstly, 3 g of sugarcane bagasse was added to DES to react for 3 hours. Subsequently, a mixture of 10 ml of water and 10 ml of acetone was added to terminate the reaction. Then it was filtered and the resulting liquid was added to a 50 ml beaker with a magnetic stirrer and heated at 105℃ at 400 rpm overnight to evaporate the water from the solution. Finally, it was removed from the thermostatic magnetic stirrer and cooled to room temperature, at which point the binder took on an amber color and flowed freely at warmth, becoming increasingly viscous as it reached room temperature. 這部分感覺描述不是很具體，求助我想復(fù)刻一下我在2.3加甘蔗渣的時候需不需要加熱呀？ |
