| titleOfInvention | A kind of preparation method of wood tar curing agent |
| abstract | The invention provides a preparation method of a wood tar curing agent, belonging to the technical field of coatings. The preparation method provided by the invention comprises the following steps: after mixing dehydrated wood tar, an alkaline solution and ethanol, dropwise addition of chloroform, and performing a reimer-tiemann reaction to obtain a reimer-tiemann reaction product; the reimer-tiemann reaction products are sequentially dissolving, acidifying, vacuum distillation, extracting organic fractions and extracting organic phase to obtain aldehyde-rich base oil; mixing the aldehyde-rich base oil and xylene to obtain a xylene solution of aldehyde-rich base oil; Sodium bicarbonate and water are mixed to carry out acid-base neutralization reaction, and after separating and extracting the organic phase, vacuum distillation is performed to obtain wood pyrool oil; after the wood pyrool oil, acrylic acid, polyethylene polyamine and xylene are mixed , dropwise adding the xylene solution of the aldehyde-rich base oil to carry out a Mannich reaction to obtain a wood tar curing agent. |
