Hello and welcome my friends from steemit in this opportunity I have titled my post "It smells like chemistry". They will ask themselves why that name as they say Chemistry, indeed, smells, and everything that smells is, indeed, Chemistry.
I would like to discuss an interesting topic, and that it falls within what I like to call "Chemistry". And is that in recent years vehicles (cars, trucks, buses, motorcycles ...) have changed our way of life and cities have had to adapt to them in every way (streets, parking, gas stations). In short, the daily image of gas stations full of vehicles is completely normal in our society, gasoline is nowadays one of the most precious products because without it our life would be impossible as we know it.
However ... do you really know what is the yellowish liquid that we put in our vehicles? Do we know how to get it? Do we know what it is composed of? Why are there different types (95, 98)? Undoubtedly, Chemistry (along with other sciences) can answer those questions, let's see.
Gasoline is a liquid composed of a mixture of hydrocarbons, obtained in the process of oil refining, whose main function is how to fuel cars.
Hydrocarbons are a family of chemical compounds that, as their name suggests, are composed of hydrogen (H) and carbon (C) exclusively. They are the basic compounds of petroleum, in which we find a great variety of them. Hydrocarbons differ in whether they form linear chains (paraffin), branched (isoparaffins), if they are cyclic (naphthenes and aromatics) or if they contain double bonds (olefins).
Gasoline is composed of hydrocarbons whose boiling point is approximately between 40 and 150 ºC, which are usually between 5 and 9 carbons. That is to say, that of all the hydrocarbons that make up the oil, this makeup gasoline.
The hydrocarbons are separated from such a complex mixture by a process called refined, said process consists of 4 stages that are the following:
Difference between gasoline 95 and 98
The 95 octane gasoline marks the minimum octane allowed. Among its advantages, we can count the best price and the ease it provides for cold starts. It is less dense, therefore lighter and is the one used in most cars.
Some advantages of this type of gasoline would be ...
98 octane gasoline, we can say that it has a higher level of refinement at the chemical level, providing a slight difference in performance and consumption, although, as we have indicated, a high power and displacement will be necessary to perceive it.
Some advantages of this gasoline would be...
