There are many types of ester based fluids and several are widely as used as lubricants, as hydraulic fluids and/or as lubricant additives. Examples include phosphate esters, diesters and polyol esters. These are used because they have performance and/or safety advantages over just mineral oil based fluids. More details later but first, esters themselves have been described as compounds formed by replacing the hydrogen of an acid by a hydrocarbon radical of the ethyl type. The name was coined by the German chemist Gmelin and was some time ago because he died in 1853. Without getting to much into the chemistry, esters can be produced by the reaction of an organic or inorganic acid with an alcohol or with another organic compound containing the hydroxyl (-OH) radical.
