Organophosphate Ester Hydraulic Fluids. Organophosphate esters are made by condensing an alcohol (aryl or alkyl) with phosphorus oxychloride in the presence of a metal catalyst (Muir 1984) to produce trialkyl, tri(alkyl/aryl), or triaryl phosphates. For the aryl phosphates, phenol or mixtures of alkylated phenols (e.g., isobutylated phenol, a mixture of several /-butylphenols) are used as the starting alcohols to produce potentially very complex mixtures of organophosphate esters. Some phosphate esters (e.g., tricresyl and trixylyl phosphates) are made from phenolic mixtures such as cresylic acid, which is a complex mixture of many phenolic compounds. The composition of these phenols varies with the source of the cresylic acid, as does the resultant phosphate ester. The phosphate esters manufactured from alkylated phenylated phenols are expected to have less batch-to-batch variations than the cresylic acid derived phosphate esters. The differences in physical properties between different manufacturers of the same phosphate ester are expected to be larger than batch-to-batch variations within one manufacturer.

Commonly used water-immiscible solvents in industrial-scale processes include alcohols (isobutanol, -butanol), ketones (particularly methyl isobutyl ketone), acetates (butyl, ethyl, isopropyl), hydrocarbons (toluene, hexanes), and methylene chloride. These solvents are inexpensive, readily available, and exhibit physical properties of low viscosity and density significantly different from water. Common water-miscible solvents are the alcohols (particularly methanol). For laboratory-scale processes, the selection is greater since selection is not constrained by economics. Craig and Sogn (16) have prepared an extensive compilation of such solvents. 

Aliphatic alcohols with appropriate hydrocarbon chain can be used as good frother. For example, 4-methyl amyl alcohol (MIBC) is widely applied in the flotation industry [3]. Aerofroth type frothers produced hy American Cyanamid Corporation belong to aliphatic alcohols. For instance, aerofroth 70 is a methyl isobutyl methyl alcohol, aerofroth 71A is an alcohol with a linear chain and an endless chain of C5-Ce, and aerofroth 77A is an alcohol with a linear chain of C4-C8. The physical properties of various aerofroth type frothers are as follows ...
