FORENSIC INVESTIGATION OF OXYGENATES IN MOTOR TYPES OF GASOLINE

The main types of oxygenates, which are used in the manufacture motor gasoline, considered. Oxygenates (oxygen-containing compounds) is general name for lower alcohols and ethers as high-octane components fuels. For a low-octane base to added. In many cases, (methanol, ethanol, etc.) (methyl tert-butyl ether, tert-amyl methyl gasoline. Straight-run gasoline stable often mixed Methanol (CH3OH) simplest monohydric alcohol. Methyl alcohol now produced synthetically from carbon monoxide (CO) hydrogen (H2). Ethanol (ethyl alcohol) representative with formula C2H5OH. production ethyl possible several ways: biochemical, hydrolysis, synthetic, or ethylene hydration. dehydrated (bioethanol, an alternative universal component fuel (KMPU), used. Bioethanol according DSTU 7166: 2010 “Bioethanol. Technical mind”. According 2010, bioethanol made biomass raw use biofuel. As technological denaturing additive, (petroleum products) introduced into amount up 1.5 % by volume. KMPU accordance TU U 20.5-00372536-001: 2013 “Component firing (KMPU). conditions”. An complex additives, Compositionally, similar but differs it presence another – ether (MTBE). CH3-O-C (CH3)3 product that can be obtained large quantities reacting isobutylene methanol. advantage MTBE its good solubility and, at same time, not washed out water. does impair physical chemical stability gasoline; characterized anti-knock properties during storage operation. article discusses results study listed oxygenates gasliquid chromatography. This method makes establish qualitative quantitative composition based on them. It shown readily available petroleum (stable gas gasoline) without equipment mixing obtain mixture high detonation resistance, fake composition. When certain proportions base, example, (lower alcohols, ethers), have appropriate performance characteristics, commercial will meet requirements regulatory documents (DSTU) considered technology also allows, when calculated A-92 (A-95) improve operational characteristics (knock resistance) increase volume resulting improving characteristics. Key words: blended ethers, bioethanol, universal.
