Cation-exchange resins as heterogeneous catalysts for the synthesis of 1,3-butadiene from propylene and formaldehyde

The possibility of using the cation-exchange resin Lewatit K2420 as a catalyst for synthesis 1,3-butadiene from isopropyl alcohol and formaldehyde solution in one technological stage has been shown. regularities process have established influence form (a cyclic trimer 1,3,5-trioxane 37% water) on composition reaction mass yield main by-products assessed. It shown that heterogeneous showed catalytic activity all reactions occurring 1,3-butadiene, including decomposition 1,3,5-trioxane, dehydration into propylene, condensation propylene formaldehyde, 3-butene-1-ol, 4-methyl-1,3-dioxane, etc.
