The catalytic process of soybean oil epoxidation with nitrous oxide is studied. There are only two phases in the process under study: liquid and gas phase N2O. In this technology there is no separation stage of water phase-oil phase. Nitrous oxide as epoxidation agent has a number of advantages: more wide range operation conditions (tem-perature, pressure) high solubility in organic substances, easy removal from product, N2O can be transported in liquefied state, provide high product selectivity. This study is divided into two parts: а) Choice of catalyst and determine of epoxidation conditions. b) software development for experiment treatment. The experiments were carried out in batch reactor of ideal mixing. There were tested catalysts ZSM-5 type modified by elements Fe, B, Na [1-2]. The experiments were carried out at 313-353 0K, pressure 0.5- 1.0 MPa. Nitrous oxide was diluted with helium by ratio 1:(3-5). The size of catalyst grains is varied from 0.1 mm to 10 mm. Experimental selectivity is 80-90 %.
