Abstract:
A highly effective scavenging additive to a leaded automotive fuel which is substantially free of carcinogenic properties comprises tribromo methane or mixtures of tribromo methane and trichloro methane.
Abstract:
Cold flow properties of fuel oils are improved by addition thereto of certain oil-soluble, pour point depressant polymers together with non-nitrogen containing, oil-soluble, auxiliary, flow improving compounds.
Abstract:
A distillate fuel having improved cold flow containing a low molecular weight product obtained on reacting an allyl halide and a C10 to C20 olefin using an aluminum halide as a catalyst, the molar ratio of allyl halide to olefin being from 5:1 to 1:10. This reaction product is characterized by having a molecular weight of from about 550 to about 1,200. A suitable allyl halide is allyl chloride; suitable olefins are decene, dodecene, tetradecene, heptadecene, octadecene and the like.
Abstract:
INCORPORATION OF SMALL AMOUNTS OF METHYL BROMIDE OR ETHYL BROMIDE, OR BOTH, INTO TETRAETHYLLEAD-CONTAINING ANTIKNOCK FLUIDS HAVING A SCAVENGER COMBINATION OF ETHYLENE DIBROMIDE AND ETHYLENE DICHLORIDE WHEREIN THE LATTER SCAVENGER PREDOMINATES. THE FLASH POINT BY TAG CLOSED CUP (ASTM DESIGNATION: D 56-64) IS RAISED TO ABOVE 100*F.
