5 5 or 6 06 ethylene glycol 10 0 or 11 03 guar gum commercial 0 2 or 0 22 ______________________________________ the sodium nitrate was dissolved first in the water and then the calcium nitrate and ammonium nitrate were added together to the solution temperature of this mixture was about 70 u00b0 c water of crystallization released from the calcium nitrate helped maintain liquidity this total mixture had a ph of about 4 5 and an oxygen balance of about 11 the guar gum was dispersed in the ethylene glycol and the resulting dispersion added to the oxidizer mixture the resulting composition was a solution having somewhat higher viscosity than an ordinary aqueous solution of the same salts it was cooled down to about 50 u00b0 c before adding particulate fuel or sensitizer ingredients in the form of various pre mixes mentioned below this solution had a 34 fudge 34 point congelation temperature of about 35 u00b0 c in order to cross link the gum to get higher viscosity and thus prevent segregation of suspended fuel particles etc a cross linking agent or in some cases a combination of oxidizer reducer agents was used a typical agent designated 34 a 34 was a 50 50 solution of potassium or sodium dichromate gallic acid or potassium antimony tartrate was used as reducing agent in a number of examples in some of these gassing agents such as nitrous acid or ammonium sodium or potassium nitrite were added in very small proportions sometimes with melamine or thiourea to accelerate aeration hydrogen peroxide was used in some cases along with traces of potassium iodide or manganese dioxide to catalyze decomposition in some.
