| Synonyms | emulsifier 37 |
| Physical and Chemical Properties | Chemical quality This product is a yellow or brown-yellow viscous liquid with a relative density (20 ℃) of 1.09~1.13. In the aqueous solution, it is in a neutral molecular or jelly state, stable to acid, alkali, and metal salt solutions, and has good surface activity at low concentrations. |
| Use | This product is widely used in pesticide emulsifier and industrial surface active agent, also used in electroplating industry, as electroplating bath additives. |
Using benzene and alkene as the alkylation reagent, it is alkylated with phenol under the catalysis of H2SO4 to obtain alkyl phenol. Then it is condensed with formaldehyde under alkali catalysis, and finally polycondensed with ethylene oxide, and then neutralized to obtain the finished product.
