Studebaker US6 2.5-ton Utility Truck (1941) JR Potts, AUS 173d AB (Updated: 7/12/2016): In April 1941, with World War in Europe on the horizon once more, the U.S. government entered into a contract with the Studebaker automobile company to begin producing 2.5-ton class military trucks out of its factory in South Bend, Indiana.
Trisodium phosphate (TSP) is the inorganic compound with the chemical formula Na 3 PO 4.It is a white, granular or crystalline solid, highly soluble in water producing an alkaline solution. TSPs are used as cleaning agent, lubricant, food additive, stain remover and degreaser.he item of commerce is often partially hydrated and may range from anhydrous Na 3 PO 4, to the dodecahydrate, Na 3 PO4 Â·12 H 2 O. Most often found in white powder form, it can also be called trisodium orthophosphate or simply sodium phosphate. Contents.
The trisodium phosphate-water binary system. In the phase diagram for the Na 3 PO 4, trisodium phosphate-water system shown to the right, one eutectic point and four peritectic points are found. The eutectic point is the cryohydratic point, where ice and Na 3 PO 4 Â·12H 2 O both are in equilibrium with the same liquid.The phase diagram consists of six different branches including ice, four hydrated forms and anhydrous trisodium phosphate.Four peritectic points mark the transitions. 1  Na 3 PO 4 Â·12H 2 O â Na 3 PO 4 Â·8H 2 O at around 54Â°C. 2  Na 3 PO 4 Â·8H 2 O â Na 3 PO 4 Â·6H 2 O at around 100Â°C.he phase diagram consists of six different branches including ice, four hydrated forms and anhydrous trisodium phosphate. Four peritectic points mark the transitions. 1  Na 3 PO 4 Â·12H 2 O â Na 3 PO 4 Â·8H 2 O at around 54Â°C. 2  Na 3 PO 4 Â·8H 2 O â Na 3 PO 4 Â·6H 2 O at around 100Â°C.
