preparation example Construction
[0041] The preparation methods of the dibenzyl ether described in the present invention are those well known to those skilled in the art. Specific preparation methods can be listed, for example: it is prepared by the action of benzyl chloride and concentrated alkali, which is also a by-product during the production of benzyl alcohol, and it can also be prepared from benzyl alcohol through etherification.
[0042]Dibenzyl ether often contains impurities such as benzaldehyde and toluene. Its purification method includes, for example, sufficient washing with sodium hydroxide solution and sodium bisulfite solution to remove benzaldehyde. After drying over potassium carbonate, toluene was removed by fractional distillation under reduced pressure. Distillation is carried out in a nitrogen or carbon dioxide stream. It can also be refined by crystallization.
[0043] Based on 100 parts by weight of the nonionic surfactant, the dibenzyl ether is 1-10 parts.
