Definitions
- the total amount of (A) dinitrophenol compound, (B) sulfonic acid compound, and (C) p-phenylenediamine compound in the polymerization inhibition method of the present invention is It depends on the conditions of the process to be performed, the degree of necessity for suppressing polymer formation, etc., and is not determined uniformly, but is generally 10 to: LO, OOOppm, preferably for the target styrenes Is from 50 to 5, OOOppm, more preferably from 100 to 3, OOOppm.
- the method for adding the dinitrophenol compound, the sulfonic acid compound, and the p-phenylenediamine compound in the present invention is not particularly limited, but usually, the ability to collectively add to a specific location, or A method of adding in a plurality of locations is appropriately selected.
- dinitrophenol compound, sulfonic acid compound and p-phenolic diamine compound are added separately, or dinitrophenolic compound, sulfonic acid compound and P-phenolic diamine compound are mixed appropriately.
- styrene for example, in the case of styrene, there is a method of adding it by dissolving in ethylbenzene or crude styrene. Any of these may be used.
- the addition location of the dinitrophenol compound, the sulfonic acid compound, and the p-phenylenediamine compound is not particularly limited, but usually divinylbenzene and an aromatic vinyl compound are copolymerized. And added to the process upstream from where the cross-linked product is formed.
- divinylbenzene and an aromatic vinyl compound are copolymerized.
- it is added to the reaction mixture after the dehydrogenation reaction of ethylbenzene, or in the distillation column feed oil for separating styrene after the dehydrogenation reaction of ethylbenzene.
- Styrene monomer, dibulebenzene (mixture of meta-form and para-form), ethylbenzene and jetylbenzene were each washed with alkali, the polymerization inhibitor contained therein was removed, washed with water and dried.
- a 4-separable flask equipped with a reflux condenser 50. Og of styrene monomer, 27.5 g of dibutylbenzene (mixture of meta and para), 11.3 g of ethylbenzene, and 11.3 g of jetylbenzene.
- the amount of deposit produced by heating the test liquid was determined as “B—A” (g).
- the resin produced is polystyrene, and polystyrene dissolves in the test solution used for the test and does not adhere to the test tube.
- dibutenebenzene styrene polymer is a cross-linked polymer, so it does not dissolve in the test solution but adheres to the test tube and becomes a deposit. The results are shown in Table 1.
- the polymerization inhibitory effect of the styrene-divinylbenzene copolymer greatly exceeds the conventional use of the dinitrophenol compound alone. It can be seen that the amount of deposits is reduced to an unpredictable extent and shows a high antifouling effect.
