Abstract

1394140 Fire fighting H C STULTS 1 May 1973 [2 May 1972] 20627/73 Heading ASA [Also in Division B1] High expansion foam producing solution for a fire fighting system is prepared from a concentrate composed of, in percent by weight from 3.0 to 4.5 percent Neodol 24, 30 to 35 percent Neodol 23-3A, 26 to 30 percent mono ether dietheolene glycol and the balance of 30.5 to 41 percent being of water. The concentrate is diluted by water to form a solution containing, in percent by volume in excess of 4 percent of the above concentrate and 96.0 percent water. Neodol 23-3A, is an aqueous solution of an ammonium salt of a sulfated primary alcohol ethoxylate containing on the average three ethylene oxide units. Neodol 23-3A has a molecular weight of approx. 423, a content of ethylene oxide by weight of 31.2 percent, a specific gravity at 25‹C of 1.01 and a pH of 7.3. It is a light coloured viscous liquid containing about 60 percent by weight surfactant and ethanol is included as a solubilizer. Neodol 25 is a blend of linear primary alcohols with 12, 13, 14 and 15 carbon atoms. The physical characteristics of Neodol 25 are a molecular weight of approx 207 a specific gravity at 35‹C of 0.834, and a viscosity of 18.3 centipoise at 100‹F.
