Abstract
A process for preparation of solution of alkaline metal polysulfide comprises interaction of elementary sulphur with solution of alkaline agent at high temperature and pressure. Elementary sulphur is delivered in melted state with content of 0.5 – 1.5 % by weight of bitumens. The solution contains at least 40 % of bitumoides. At that, sulphur solution before delivery is kept at the temperature above the point of melting thereof during 1.0 – 2.5 days and it is introduced into the solution heated to 108 – 120 °C.
