SULPHUR CEMENT PRE-COMPOSITION AND PROCESS FOR PREPARING SUCH SULPHUR CEMENT PRE-COMPOSITION

摘要

The present invention provides a sulphur cement pre- composition, comprising sulphur and at least an organotitanate, which organotitanate is of the general molecular formula (1): wherein R1 is CnH(2n) -<sub/>SaR4 or CmH(2m+1) and n is an integer in the range of from 1 to 4, m is an integer in the range or form 1 to 30 and a is an integer in the range of from 2 to 8, R4 is S, H, or CpH(2p+1) and p is an integer in the range of from 1 to 8, XO is an alkoxy or neoalkoxy group, R2 and R3 are, independently, a CnH (2n) - SaR4, alkyl, neoalkyl, acyl or aryl group. The invention further provides a process for preparing such sulphur cement pre-composition, processes for the preparation of a sulphur cement product, a sulphur cement product and the use of such sulphur cement pre-composition. The invention even further relates to the use of an organotitanate stabilizing agent.
