34gNaOH is added in the step C in the reactant of step B, 50 DEG C of reaction temperature is handled 2.5 hours.
Beneficial effects of the present invention are：
1, stalk is pre-processed, by ethyl alcohol and NaOH basifications, then carries out monoxone etherificate, weak base state
Lower standing is added dropwise weak acid and neutralizes.Stalk is by above-mentioned processing viscosity up to 25mps or more (mass percent 4%).It can be used as painting
Feed additives use, and have widened stalk recycling and have used field.
2, coating processing cost is reduced by recycling stalk, the present invention uses dry technology for production.Low cost is can get, is fitted
Coating emulsion is done in conjunction, and then produces stalk coating.
