Abstract
Epoxide functionalized polyaromatic feedstocks and processes for their preparation are described. The processes involve functionalizing polyaromatic hydrocarbon molecules and/or polyheterocyclic molecules present in petroleum or petrochemical streams with epoxide. The epoxide functionalized poly aromatic feedstock can be further treated so as to effect oligomerization or polymerization. The oligomers or polymers may be thermoplastic or thermoset materials and may find use in, for example, infrastructure applications, composites, fillers, fire retardants and 3-D printing materials.
Claims14
A process for, wherein the feedstock comprises vacuum residue, fluidic catalytic cracking (‘FCC’) bottoms, steam cracker tar, asphaltenes, C3-C7 rock, bitumen, K-pot bottoms, lube extracts, or a combination thereof, comprising:
- contacting the feedstock with an epoxidizing reagent comprising a peracid, a peroxide, a halohydrin, dimethyldioxirane, or a combination thereof, at a temperature of 150° C. or less to form an epoxide functionalized aromatic feedstock comprising 1 wt % to 80 wt % of epoxidized polyaromatic hydrocarbons, epoxidized polyheterocyclic compounds, or a combination thereof,
- comprises polyaromatic hydrocarbons, polyheterocyclic compounds, or a combination thereof comprising two or more double bonds having olefinic character so that multiple carbon-carbon double bonds form multiple epoxide functionalization in contact with the epoxidizing reagent,
- wherein a polyaromatic hydrocarbon is a hydrocarbon having at least two rings, at least one of which is aromatic, and
- wherein a polyheterocyclic compound is a compound having at least two rings, at least one of which is aromatic, and having at least one aromatic ring that contains one or more heteroatoms selected from sulfur, nitrogen, oxygen, or a combination thereof.
