Catalyst for synthesizing heterogeneous alcohol polyoxyethylene ether |
| abstract |
The invention relates to a catalyst for synthesizing heterogeneous alcohol polyoxyethylene ether. The technical scheme includes that the catalyst comprises calcium acetate and o-hydroxybenzoic acid in the weight ratio of 1:0.05-3. The heterogeneous alcohol polyoxyethylene ether prepared by the catalyst as compared with the prior art has the advantage of narrow molecular weight distribution. |
