摘要：
A modified synthesis of 1-butyl-3-methylimidazolium bromide (BMImBr) was suggested and performed, and some physicochemical properties of the product containing 0.64-13.6 wt % water were determined. Water increased the electrical conductivity and decreased the viscosity and melting point of the substance but weakly influenced its density. Water in amounts of 5-8 wt % (45-50 mol %) caused structural changes. The BMImBr center dot 0.5H(2)O crystal hydrate was found to be stable thermodynamically.
