| titleOfInvention | Method for producing dialkylnaphthalene |
| abstract | (57) [Summary] (Modified) [PROBLEMS] To establish a method for producing dialkylnaphthalene from a large amount of petroleum-based raw materials. SOLUTION: The method for producing dialkylnaphthalene includes the steps of 1), 2), 3) and 4). 1) A feedstock containing a significant amount of naphthalene and / or alkylnaphthalene is subjected to catalytic hydrodealkylation reaction, and the product gas and product oil are subjected to gas-liquid separation to produce a product mainly composed of naphthalene and / or methylnaphthalene from product oil. Separating and collecting the minute. 2) A step of producing an alkylnaphthalene by directly subjecting the fraction collected in 1) to catalytic alkylation or catalytic transalkylation together with an alkylating agent or a transalkylating agent without going through a pretreatment purification step. 3) A step of separating and recovering dialkylnaphthalene from the alkylnaphthalene obtained in 2). 4) Part or all of the fraction obtained after separating and recovering the dialkylnaphthalene in 3), part or all of the feedstock of 1) and / or part of the alkylating agent or transalkylating agent of 2). A step of returning to each step as a whole. |
