1 Claim.
This invention relates to a means and method, or process, of treating and preparing what are commonly called, tars, compounds of tar, oils, asphalts, asphaltic compounds, petroleum and/or 5 petroleum compounds for emulsification and con sists particularly in preparing such products so that such products Will almost instantly pass into a state of emulsion when poured into and mixed, in any suitable manner, with water containing no antagonistic elements or in which water the antagonistic elements have been rendered inert, and/or with alkaline water containing no antagonistic elements or in which the antagonistic elements have been rendered inert.
It is the prime feature of this invention to so prepare what are commonly called tars, compounds of tar, oils, asphalts, asphaltic compounds, petroleum and/or petroleum compounds and especially what are commonly known as and 20 in trade called road oils, comprising tars, compounds of tar, oils, asphalts, asphaltic compounds, petroleum and/or petroleum compounds consisting in all or in part of non-volatile ingredients, for emulsification.
The preferred process for treating such materials is to add thereto substantially one half /2%) per cent, minus, to two (2%) per cent, plus, by volume as a minimum of selected anhydrous acid, or anhydrous to such an extent that 30 it will mix with and will assimilate with the material to be emulsified, such as anhydrous acetic acid, or acetic anhydride. It is impossible to define precisely the range of variations of the above percentages, as such percentages are influenced by the varying natures or compositions of the asphaltic and petroleum oils, but the percentages given will be found to give satisfactory results with many specimens of asphaltic and 5 petroleum oils. Such forms of acid perfectly mix and perfectly assimilate with all varieties of such materials and renders them ready for emulsification. By adding such acids to such specified materials, such materials are rendered 1o susceptible to combination with alkaline materials, such as caustic soda or sodium carbonate,
or the like. When any of the above materials,
so prepared with such forms of acid, are poured into and/or mixed with water rendered alkaline 15 and free from competing or incompatible materials; such as lime, magnesia, and the like, such materials will be broken into a state of extremely fine dispersions and the dissemination will be so complete that the materials treated with such forms of acid and the water above specified will, with slight agitation almost instantly enter a state of emulsification.
What I claim is:-
A method of preparing a bituminous emulsion which consists in adding to material of the group consisting of asphalt and petroleum oils substantially one half /2 percent to substantially two (2%) percent by volume anhydrous acetic acid, adding thereto an aqueous alkaline solution free from alkaline earth compounds, then thoroughly agitating the same to produce an emulsion.
