| 摘要 | A method for producing an APL is provided in one example embodiment and includes mixing a solvent, a catalyst, a reagent, and a HPL to create a solution, raising the temperature of the solution to a first reaction temperature, raising the temperature of the solution to a second reaction temperature, allowing reactions in the solution to occur for a predetermined amount of time, precipitating the solution to produce a precipitate, and washing, filtering, and drying the precipitate to produce the APL. | ||

| 主权项 | 1. A method for producing an acetyoxypropyl lignin (APL), comprising: mixing a solvent, a catalyst, a reagent, and a hydroxypropylated lignin (HPL) to create a solution; raising a temperature of the solution to a first reaction temperature; raising the temperature of the solution to a second reaction temperature; allowing reactions in the solution to occur for a predetermined amount of time; precipitating the solution to produce a precipitate; and washing, filtering, and drying the precipitate to produce the APL. | ||
