TECHNICAL FIELD

[0001] The utility model relates to the technical field of isocyanuric acid triglycidyl ester production, especially to a kind of isocyanuric acid triglycidyl ester production catalyst dosing control reaction kettle. BACKGROUND

[0002] Industrial production of isocyanuric acid triglycidyl ester mainly adopts two-step process, the first step is synthesis reaction: epichlorohydrin and cyanuric acid, under the action of catalyst, ring-opening reaction is carried out, and ternary chlorohydrin is generated. The second step: the generated ternary chlorohydrin reacts with sodium hydroxide, and the chloride ion is removed, and the TG I C is cyclized.

[0003] In the first step of synthesis reaction process, the type, quantity and dosing method of catalyst have great influence on the whole process, and we have studied the compound catalyst process through experiment, and the whole process is as follows:

[0004] ①The catalyst used in the synthesis process is mainly quaternary ammonium salt, among which benzyltrimethylammonium chloride has high reaction activity, and the cooling system of the synthesis equipment is required to be high in high-temperature weather, benzyltriethylammonium chloride has stable activity and temperature control safety; tetramethylammonium hydroxide has less residue in finished product, but the catalytic effect is weak. In order to improve product quality and process safety, under the condition that the mole number of raw material ratio is unchanged, benzyltrimethylammonium chloride, benzyltriethylammonium chloride and tetramethylammonium hydroxide are added in a certain proportion, two or three of the above catalysts are added in each batch, the process safety is improved by compounding catalyst, and the product quality is improved.

[0005] ②In the synthesis process of isocyanuric acid triglycidyl ester, we improve the dosing method of catalyst; in the original process, after the catalyst is dissolved in water, after the cyanuric acid is added, it is added to the synthesis reaction kettle at one time. Now it is added in dropwise manner, cyanuric acid and excess epichlorohydrin are stirred and heated to 65 DEG C, heating is turned off, and catalyst is started to be added dropwise, which is completed within one and a half hours, and the material is controlled to be slowly heated to 105 DEG C. This process only heats the synthesis material once, and the heat generated during the reaction process promotes the temperature rise of the material, compared with the original two-time heating, a large amount of steam is saved.
