Use of ethers as high-octane components of gasolines
This article reports on a study of the possible utilization of methyl tert-amyl ether (MTAE) as an automotive gasoline component, both by itself and in combination with methyl tert-butyl ether (MTBE). The naphtha used in these studies consisted of 80% reformer naphtha produced under severe conditions and 20% straight-run IBP-62/sup 0/C cut. The physicochemical properties of the MTAE, the MTBE, and the naphtha base stock are given. It is determined that MTAE, which has a slightly poorer knock resistance than MTBE, is fully equal to MTBE in all other respects and can be used as an automotive gasoline component; that a gasoline blend prepared from 89% naphtha base stock, 5.5% MTAE, and 5.5% MTBE meets all of the requirements of the standard GOST 2084-77 for Grade AI-93 gasoline; and that the use of MTAE offers a means for expanding the resources of high-octane components, lowering the toxicity of the gasolines and the exhaust gas (in comparison with organometallic antiknock agents), and bringing non-petroleum raw materials into the fuel production picture.
