Title (EN) METHOD FOR PREPARING LOW-MOLECULAR LIGNIN DERIVATIVE
(FR) PROCÉDÉ DE PRÉPARATION DE DÉRIVÉ DE LIGNINE DE FAIBLE POIDS MOLÉCULAIRE
(KO) 저분자 리그닌 유도체의 제조방법
Abstract: front page image
(EN)Provided is a method for preparing a low-molecular lignin derivative, comprising the steps of: preparing lignin obtained by hydrolyzing lignocellulosic biomass with acid; preparing a first mixture by mixing 100 parts by weight of the lignin and 500 parts or more by weight of a phenol-based compound; preparing a second mixture by mixing the first mixture with a solvent containing the hydrophobic polar solvent; and collecting a low-molecular lignin derivative from the second mixture.
(FR)L'invention concerne un procédé de préparation d'un dérivé de lignine de faible poids moléculaire, constant à : préparer de la lignine obtenue par l'hydrolyse d'une biomasse lignocellulosique au moyen d'un acide ; à préparer un premier mélange par le mélange de 100 parties en poids de la lignine et 500 parties en poids ou plus d'un composé à base de phénol ; à préparer un deuxième mélange par le mélange du premier mélange avec un solvant contenant le solvant polaire hydrophobe ; et à recueillir un dérivé de lignine de faible poids moléculaire à partir du deuxième mélange.
(KO)목질계 바이오매스(lignocellulosic biomass)를 산으로 가수분해하여 얻어지는 리그닌을 준비하는 단계; 상기 리그닌 100 중량부와 500 중량부 이상의 페놀계 화합물을 혼합하여 제 1 혼합물을 준비하는 단계; 상기 제 1 혼합물을 상기 비수성 극성용매를 포함하는 용매와 혼합하여 제 2 혼합물을 준비하는 단계; 및 상기 제 2 혼합물로부터 저분자 리그닌 유도체를 회수하는 단계;를 포함하는 저분자 리그닌 유도체 제조방법이 제공된다.
