Abstract
Homogeneous sulfur-hydrocarbon blends comprising a continuous sulfur matrix containing hydrocarbon, and methods of manufacture and use are described. These materials are particularly suitable as soil supplements, for comminution, or for compounding with hydrophobic materials such as elastomers and oil-based paints. Several advantages are apparent in essentially any application involving storage or transport.
Claims9
The method of producing a homogeneous hydrocarbon-sulfur fusion comprising a continuous rhombic sulfur matrix and at least 0.2 weight percent of a hydrocarbon, based on the combined weight of said sulfur and hydrocarbon, said hydrocarbon being uniformly dispersed within said sulfur matrix, said method including the steps of forming a homogeneous melt comprising at least 60 weight percent elemental sulfur based on the weight of said fusion and at least about 0.2 weight percent of said hydrocarbon, based on the combined weight of said sulfur and hydrocarbon, at a melt temperature of 120.degree. to about 400.degree. C., and solidifying said homogeneous melt to form said homogeneous fusion, said hydrocarbon being non-reactive with said sulfur at said melt temperature and having a melting point below said melt temperature and a boiling point above said melt temperature.
The composition of matter comprising a homogeneous hydrocarbon-sulfur fusion comprising a continuous rhombic sulfur matrix containing a hydrocarbon non-reactive with sulfur uniformly distributed throughout said continuous sulfur matrix and containing at least about 60 weight percent rhombic sulfur based on said fusion and at least about 0.2 weight percent of said hydrocarbon based on the combined weight of said sulfur and hydrocarbon.
