使用盐酸异丙醇滴定法和烘箱干燥法对不同用量二乙烯三胺制备得到的黑液木质素基酚醛胺固化剂胺值和固含量测定。 胺值：样品质量1~4g；固含量：样品1±0.1g、125℃、1h。黑液木质素基酚醛胺固化剂的制备：黑液木质素、甲醛、二乙烯三胺，温度85℃，时间4h

The amine value and solid content of lignin-based phenolic amine curing agent in black liquor prepared with different dosage of diethylenetriamine were determined by titration of isopropyl alcohol hydrochloride and oven drying. Amine value: sample mass 1~4g; Solid content: Sample 1±0.1g, 125℃, 1h. Preparation of black liquor lignin-based phenolic amine curing agent: black liquor lignin, formaldehyde, diethylenetriamine, temperature 85℃, time 4h.
