摘要:
Compounds, synthesis of, and methods for synthesizing metal alkoxide derivatives; and metal alkoxide derivatives for use as flame retardants are described. Group 13 metal alkoxides having flame retardant properties may be prepared by reacting the group 13 metal trihydroxide with an alcohol.
摘要:
A method of upgrading a heteroatom-containing hydrocarbon feed by removing heteroatom contaminants is disclosed. The method includes contacting the heteroatom-containing hydrocarbon feed with an oxidant and an immiscible acid to oxidize the heteroatoms, contacting the oxidized- heteroatom-containing hydrocarbon feed with caustic and a selectivity promoter, and removing the heteroatom contaminants from the heteroatom-containing hydrocarbon feed. The oxidant may be used in the presence of a catalyst.

A compound of Formula (II) and (III), or a mixture of any two or more thereof; wherein M is Ti or Zr; R3 at each occurrence is H, F, Cl, Br, I, CN, OR4, NR5R6, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylalkyl, unsubstituted heterocyclyl, or substituted or unsubstituted heterocyclylalkyl; R4 is H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted cycloalkylalkyl, unsubstituted heterocyclyl, or substituted or unsubstituted heterocyclylalkyl; R5 and R6 are independently H, substituted or unsubstituted alkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocyclylalkyl, or R5 and R6 may join to form a heterocyclic ring containing the N to which they are attached; and n′=0-4. Such compounds form optically transparent and/or clear films or particles or may be used to prepare such materials.

摘要:
Catalysts amenable to oxidizing sulfur compounds and systems and methods of using these catalysts to effect the removal of sulfur from crude oil and crude oil distillates are disclosed. The catalyst is disposed with a titanyl moiety which serves to selectively coordinate sulfur compounds and affect their oxidation. The titanyl may be bound within a polymer or on the surface of a polymer or on the surface or in the pores of an inorganic support. The resulting oxidized sulfur compounds are readily separated from the initial crude oil or crude oil distillate streams by traditional separation techniques arrayed as described in the systems and methods disclosed.
