Embodiment
[0011] The synthesis technique of the gas-phase method vulcanized isobutylene of the present embodiment comprises the following steps:
[0012] (1) Stir and mix elemental sulfur and catalyst at 460°C-550°C and 3MPa-5MPa for 10min-20min to obtain a mixed gas phase stream;
[0013] (2) Pass in isobutene gas and mix with the mixed gas-phase stream obtained in step 1) to form a gas-phase mixture and enter the reactor to react for 10min-20min under the conditions of 450°C-500°C and 2MPa-9MPa to obtain the reaction product;
[0014] (3) The reaction product obtained in step 2) is cooled and subjected to gas-liquid separation, and the liquid phase is filtered to obtain a sulfurized isobutylene product.
[0015] The gas-phase sulfurized isobutylene synthesis process does not require further processing, the process is simple, the data is accurate and easy to measure, and the process flow is easy to implement.
