Definitions

• a further object of this invention is to provide a method for adding a bactericide to petroleum and petroleum fractions which substantially completely eliminates the need for aqueous solutions.
• the invention then comprises the features hereinafter fully described and particularly pointed out in the claims, the following description setting forth in detail certain illustrative embodiments of the invention, these being indicative, however, of but a few of the Ways in which the principle of the invention may be employed.
• the present invention comprises the method of preventing bacterial action in stored petroleum which comprises adding to said stored petroleum a liquid alkali metal organoborate selected from the group consisting of the condensation products of an alkali metal borate and a material selected from the group consisting of an ethylene glycol, diethylene glycol, triethylene glycol, 1,4-butanediol, 2,3-butanediol, and 1,2-propanediol, said glycol borate condensation products consisting essentially of a mole ratio of from about 6:1 to about 20:1 of diol to equivalent alkali metal tetraborate, and said condensation products added to tank in bactericidal amounts.
• a liquid alkali metal organoborate selected from the group consisting of the condensation products of an alkali metal borate and a material selected from the group consisting of an ethylene glycol, diethylene glycol, triethylene glycol, 1,4-butanediol, 2,3-butanediol, and 1,2-
• the glycol borate condensation product is added in an amount equivalent to that amount necessary to completely cover the bottom of the tank to be protected against bacterial action. If the tank is substantially water-free, an amount of condensation product is added which would substantially completely cover the bottom of the tank. If the tank already contains water, an amount of condensation product is used which is equivalent to that amount necessary to substantially completely cover the bottom of the tank if no water were present.
• petroleum as used herein, is intended to include crude oil, kerosene, gasoline, lubricating oils, diesel fuels, and the like, as well as other hydrocarbons that are susceptible to bacterial degradation during storage.
• condensation products useful in the present inven tion are readily prepared using condensation processes well known to those skilled in the art.
• the condensation product of sodium tetraborate and ethylene glycol is simply prepared by adding 1.0 mole of borax and 9.0 moles of the glycol to a reaction vessel and heating it to about to C. for sufiicient time to drive out water and give a product having a 9:1 mole ratio of glycol to equivalent sodium tetraborate.
• the condensation product is a clear liquid which can be added directly to the petroleum storage tank.
• the present invention has provided an efficient means for inhibiting bacterial growth in storage tanks, and which means is independent of the amount of Water present in the storage tank.
• the present products are substantially inert with respect to the liquid contained in the storage tank and they are substantially completely compatible with any water which may be present in the tank.
• the improvement which comprises adding to the stored petroleum in bactericidal amounts a liquid alkali metal glycol borate having an alkylene group of 2 to 6 carbon atoms in length and containing a total of 2 to 20 carbon atoms.
• liquid alkali metal glycol borate selected from the class consisting of sodium ethylene glycol borate, potassium ethylene glycol borate, sodium dietbylene glycol borate, potassium diethylene glycol borate, sodium 1,2-propanediol borate, potassium 1,2-propanediol borate, sodium 2,3-butanediol borate, potassium 2,3-butanediol borate, sodium 1,4-butanedio1 borate, potassium 1,4-butanediol borate, and sodium triethylene glycol borate.
• a composition comprising a major proportion of petroleum in contact With an aqueous phase and tending to undergo degradation and to deposit a sludge due to the presence in at least one of said petroleum and said aqueous phase of microorganisms that promote degradation of petroleum and a bactericidal amount of a liquid alkali metal glycol borate having an alkylene group of 2 to 6 carbon atoms in length and containing a total of 2 to 20 carbon atoms.
• composition of claim 3 where said alkali metal glycol borate comprises sodium ethylene glycol borate.
