Abstract
Abstract of the Disclosure This invention relates to a method of preparing a highly concen-trated, stable polyborate solution, characterized in that boric acid is reacted with an alkanolamine or an aliphatic polyamine or a mixture thereof in the ratio base to boric acid of 1 to more than 2 in order to give a boric acid concentration of over 30 g/100 ml when the solution has been made up to 100 ml with water.
Description
~L~13;Z'~3~
The present invention concerns highly concen-trated polyborate solutions which are obtained in liquid form and resistant to extreme cold. The present invention also concerns a method of preparing such highly concentrated polyborate solutions.
The preparation of concentrated, liquid borate solutions is important for borate-containing textile auxiliaries such as yarn moistening agents, for metal-~ working agents such as coolants and for liquid cleaners and disinfectants which are intended to be provided in concentrated, liquid form.
Of the known salts of boric acid and the poly-boric acids, the potassium salts are the most readily so-luble but none of these salts has a solubility of more than 10 % in water at 0 C which is insufficient for the applications mentioned above~
The aim of the invention is to prepare poly-borate solutions which are obtained in highly concentrated, liquid form, are resistant to extreme cold and are odourless.
The theoretical aspects of polyborate solution chemistry are described in "Handbuch der anorganischen Chemie" by Gmelin-Kraut.
Attempts to use aliphatic amines-as bases for borates surprisingly showed that alkanolamines (preferably . . . ~
.
.
/
23~
monoethanolamine) and aliphatic polyamines (preferably triethylene tetramine) form very readily water-soluble polyborates with boric acid. 1 mole of monoethanolamine can bring 3 to 4 moles of boric acid into solution, and a solution containing 20 g of the base can also contain up to 60 - 70 g of boric acid after being made up to 100 ml with water. A solution made in this way is not viscous and does not solidify at very low temperatures such as -10 C, Similarly, with triethylene tetramine as the base, a solution made up to 100 ml with water can contain 60 to 70 g of boric acid when 17 g of the base are used.
This solution solidifies at a temperature as high as 0 C
though. Mixtures of the two solutions, however, show sa-tisfactory behaviour at low temperatures again, not even solidifying at -10 C.
The solutions of the invention possess the pro-perty that their pH in concentrated solution is weakly acid (pH - approx. 6), but in dilute solùtions it is alkaline (pH = 8.5 to 8.9).
A polyborate solution of boric acid and mono-ethanolamine is insensitive to the addition of methanol.
A solution can be produced containing 50 g of boric acid and 17 g monoethanolamine made up to 100 ml with pure methanol. The viscosity of this solution is significantly hish~r than that of the a~ueous solution ho~ever.
,.
23~
Example 1 60 g boric acid are reacted with 20 g of monoethanolamine and made up to a volume of 100 ml with water. When stirred, the boric acid goes into solution almost instantaneously, a small amount of heat being evolved. This solution is miscible with methanol and does not solidify at temperatures as low as -10C.
Similar results are obtained if isopropanolamine is used instead of ethanolamine.
Exa ~ 2 S0 g of boric acid are reacted with 12 g of triethylene tetramine and made up to a volu~e of 100 ml with water. The boric acid dissolves very quickly. The solution solidifies to give crystals at 0C however.
Exame_e 3 Equal volumes of the solutions of Examples 1 and 2 are mixed. `~
The solution thus obtained does not solidify at temperatures as low as 10C~
