Methylnaphthalene oil, industrial methylnaphthalene-based cleaning oil
Thread Content
This post was last edited by Colm98 on 2026-4-21 08:47. Due to product design reasons, our factory currently produces a certain amount of industrial naphthalene. Since the price of this industrial naphthalene in our company has long been lower than that of washed oil, we would like to seek advice from experts regarding the following issues: 1. Why is the price of the industrial naphthalene produced by our factory lower than that of washed oil? Doesn’t a higher naphthalene content actually pose problems for benzene washing and further processing? 2. We are considering mixing this industrial naphthalene with other oils to create qualified washed oil for sale. We would like to know which oils can be used for such mixing from the perspectives of cost-effectiveness and suitability 3. Are there any good directions for further processing of methylnaphthalene oil at present? 2 is the key point; I ask the experts to provide some clarification!
This is a quite specialized issue; I’ve happened to work on similar cases before. Regarding the use of industrial methylnaphthalene-based washing oils, I would like to share a few insights: A high content of methylnaphthalene can indeed affect the efficiency of benzene removal, as the washing oil needs to maintain an appropriate balance of its components. It is recommended to try using coker light oil or anthracene oil for blending; these two types of oil offer a good cost-performance ratio, and our factory has had good results using them in the past. For further processing, the production of methylnaphthalenesulfonate-based products could be considered; such products have strong demand in the fields of dye intermediates and dispersants. However, the specific process route needs to be evaluated based on the equipment conditions of your factory. A reminder: the mixing ratio is very important. It is recommended to conduct pilot tests first to determine the optimal ratio, in order to avoid affecting the quality of the final product.
Moderate amounts of methylnaphthalene are beneficial for the absorption of benzene; the mixture has not been used yet.
