为了研制一种优质低价的减水剂,我们采用镇江焦化厂脱萘脱酚后余下的中油加入少量萘残油,代替萘和甲基萘,进行减水剂合成试验,终于初步试制成功高效能减水剂—JN。JN 减水剂质量稳定,效能较好,合成时采用了新的磺化工艺,合成工艺流程见图3。 In order to develop a high-quality, low-cost water reducer, we used a small amount of naphthalene residual oil after the naphthalene dephenol was removed from Zhenjiang Coking Plant to replace naphthalene and methylnaphthalene, and conducted a water-reducing agent synthesis test, and finally the preliminary trial was successful and efficient. Reducing agent - JN. JN water-reducing agent is of stable quality and good performance. A new sulfonation process is used during synthesis. The synthesis process is shown in Figure 3.
