摘要:以 1-(2-呋喃基)-3-苯基-2-丙烯-1-酮(FPPO)、过氧化氢、硫脲为原料,以四丁基溴化铵为催化剂,采用
一锅法合成 2,3-环硫-1-(2-呋喃基)-3-苯基-1-酮(TFPO)。通过单因素实验,考察了时间、温度、氧化剂用量、
催化剂用量等对 TFPO 产率的影响,进一步利用正交实验优化法对合成 TFPO 的工艺参数进行优化。结果表明,
合成 TFPO 较佳的工艺条件为:环氧化温度为 5 ℃,硫化时间为 2 h,硫化温度为 35 ℃,n(硫脲)∶n(FPPO)=1∶
1,催化剂用量为 15.5%(以 FPPO 物质的量为基准计算得到,下同)。在该条件下,TFPO 产率为 85.8%。采用

Abstract: 2,3-Thiirane-1-(2-furyl)-3-phenyl-1-one (TFPO) was synthesized via one-pot reaction with
1-(2-furyl)-3-phenyl-2-propen-1-one (FPPO), hydrogen peroxide, thiourea as raw material, and
tetrabutylammonium bromide as catalyst. Based on the influence regular of TFPO yield, several parameters
such as time, temperature, oxidant dosage and catalyst dosage were screened by single factor experiments.
And then the orthogonal optimization method was used to in optimize its process parameters. Finally, the
optimal synthesis conditions for TFPO were determined as follows: epoxidation temperature is 5 ℃,
vulcanization time is 2 h, vulcanization temperature is 35 ℃, the molar ratio of FPPO to thiourea is 1∶1,
and catalyst dosage is 15.5%. The yield of TFPO was 85.8% under the above optimized reaction conditions.

The structure of TFPO was confirmed by FTIR, HNMR and CNMR, and TGA, UV were applied to test
the perormance of TFPO. The TGA test results showed that the heat resistance temperature of TFPO was
160 ℃ and showed good thermal stability. The UV test results showed that the transmittance of TFPO was
over 90% and has excellent light transmission properties.
