Description

The primary aim in the worldwide market at the moment is to limit the amount of dangerous emissions into the atmosphere. Transportation accounts for over one-third of all greenhouse gas emissions. As a result, alternative sources can dramatically lower the environmental burden while also expanding the resource base in an unpredictable oil market.

The main component of products derived from alternative resources is oxygen. The inclusion of oxygen in the molecule helps to improve some operational conditions while also taking environmental considerations into note (harmful emissions can be minimized due to a more efficient combustion process).

Alcohols such as methanol, ethanol, butanol, and isopropanol have been identified as potentially useful fuels. Ethanol, which has a high research octane, is a carbon-neutral fuel. Blended gasoline-ethanol fuels are widely utilized around the world. At the same time, alcohol content in fuels is restricted since excessive amounts can cause substantial drawbacks such as phase instability, water solubility, poor combustion heat and vapour pressure, and corrosive activity. Using methanol as a gasoline additive also causes engine wear.

Esters are employed in both petrol and diesel engines. Simple ethers derived from renewable elements, such as dimethyl ether, diethyl ether, diethyl adipate, diethyl carbonate, and ethyl butyrate, have recently received special attention. Esters provide effective anti-knock properties, enable more complete fuel combustion due to their high oxygen content, and protect against corrosion of metal surfaces and the formation of solid carbon deposits on cylinder walls. Additionally, the environmental impact is kept to an absolute minimum when they are destroyed. However, the physicochemical properties of ethers differ greatly from those of ordinary fuels, causing engine operation challenges. In this sense, heavier counterparts of dimethyl ether could be used.

As fuel additives, aliphatic acetals (linear or cyclic) constitute a possible feedstock. When linear acetals with low-molecular-weight saturated or unsaturated branches are added to petrol, it retains its phase stability after contact with water, has higher detonation resistance and has a high octane number. Acetals, ketals, or their mixtures with boiling points ranging from 40°C 5°C to 170°C 10°C are used as octane boosters in spark ignition engines, and with boiling points ranging from 170°C 10°C to 330°C 20°C in compression ignition engines.

Because of their hydrophobic behavior, cyclic acetals with a 1,3- dioxolane and 1,3 dioxane structure are also recommended for blending with diesel fuel, offering increased cetane number and density, as well as decreased viscosity, freezing point, and soot production. Particulate emissions are also being reduced.

Considering the foregoing, the research topic of synthesis and application of new renewable oxygen-containing additives, primarily acetals, for fuel from alternative resources is in high demand. This study focuses on unsaturated branching hydrocarbons as a potential feedstock, namely isoprene (2- Methylbuta-1, 3-diene), a simple monomeric five carbon building block for a variety of naturally occurring chemicals. Isoprene is produced commercially as a byproduct of crude oil refining or ethylene manufacture (800,000 tonnes per year).

It is commonly used as a feedstock in the synthetic chemical industry, such as rubber. It does, however, have tremendous potential because plants and animals can synthesize this key molecule and provide renewable drop-in biofuel isoprene sources. Because of the existence of a double bond and a branched chain structure, it is simple to build ring structures, which results in the formation of second-order fuel molecules for petrol, jet fuel and diesel. Other reagents used in this study, such as ethanol, acetaldehyde, and acetic acid, can also be commercially generated from biomass. An examination of the literature revealed a dearth of research in this field, specifically in the manufacture of oxygenate additions from isoprene and ethanol.
