摘　　要：研究用洗油代替部分工业萘合成高效减水剂的工艺。研究了磺化反应、缩合反应及洗油替代量对产品性能的影响。结果表明,洗油替代量30%、在160℃下磺化2.5h、缩合4.5h条件下,可得到与萘系减水剂(NF)性能相当但减水率略高、早期强度高且成本较低的NF30高效减水剂。在原料中加入氧化剂MO可以减少反应中酸性气体的排放。The article deals with the synthetic process of high-range water reducing agent with wash oil that replaces part of crude naphthalene. It studies the influence of sulfonation reaction, condensation reaction and proportion of wash oil on the properties of the synthetic agent. The result indicates that NF30 high-range water reducing agent can be made when wash oil takes 30% of crude naphthalene under a temperature of 160℃ and sulfonation reaction for 2.5h and condensation reaction for 4.5h. Comparatively, NF30 owns the same property with NF but enjoys a higher early strength and low cost. It also proposes that adding some oxidant of MO helps to reduce the emission of acid gas.
