Abstract Two kinds of mixed gases, one of water vapor and sulfur vapor and the other of water vapor and butadiene, are preheated in the preheating section simultaneously and then reacted in the heating reaction section to obtain thiofuran semiproduct. The thiofuran semiproduct is further processed in the sectional reactor finally to obtain product with high purity at high yield and low cost.
