Example Embodiment
[0015] Example 1
[0016] 1) Add 300L of concentrated sulfuric acid into the reaction kettle, add 200L of concentrated nitric acid dropwise within 60min under vigorous stirring, the temperature is controlled below 35℃, and then add 350L of isooctyl alcohol dropwise during 60~70min, the temperature of the dripping process is controlled at 40℃ Below, after the addition, the reaction was kept at 45°C for 60 minutes. Wash in cold water to obtain crude isooctyl nitrate.
[0017] 2) At room temperature, add 20% ammonia water 100Kg to 500Kg crude isooctyl nitrate, heat up to 58°C, react for 2h, then lower the temperature to 20°C, stand for layering, wash with water until neutral, to obtain the finished product of isooctyl nitrate , The acid value is 1.5KOH / 100ml, the acid value is 1.5KOH / 100ml after two months, and the acid value is 1.5KOH / 100ml after six months.
Example Embodiment
[0020] Example 2
[0021] Start from step 2): At room temperature, add 200Kg of 20% ammonia water to 1000Kg of crude isooctyl nitrate, heat up to 60°C, react for 2h, then cool to 20°C, stand for stratification, wash with water to neutrality to obtain nitric acid The acid value of the finished product of isooctyl ester is 2.2KOH / 100ml. After two months, the acid value is 2.2KOH / 100ml, and after six months, the acid value is 2.2KOH / 100ml.
[0022] The finished product of isooctyl nitrate has an acid value of 2.2KOH / 100ml. After two months, the acid value is 6.7KOH / 100ml, and after six months, the acid value is 8.0KOH / 100ml.
