The Northern Pacific Railway was the first railroad to order a 2-8-8-4. The first was built in 1928 by American Locomotive Company; at the time, it was the largest locomotive ever built. It had the largest firebox ever applied to a steam locomotive, some 182 square feet (16.9 m 2) in area, to burn Rosebud coal, a cheap low-quality coal.
2-8-8-8-4. Under the Whyte notation for the classification of steam locomotives, a 2-8-8-8-4 has two leading wheels, three sets of eight driving wheels, and four trailing wheels . The equivalent UIC classification is to be refined to (1'D)D (D2') for these engines. Only one 2-8-8-8-4 was ever built, a Mallet -type for the Virginian Railway in ...
The 2-8-8-2 was a design largely limited to American locomotive builders. The last 2-8-8-2 was retired in 1962 from the N&W's roster, two years past the ending of steam though steam was still used on steel mill lines and other railroads until 1983. A similar wheel arrangemement exists for Garratt locomotives, but is referred to as 2-8-0+0-8-2 ...
Solketal is a protected form of glycerol with an isopropylidene acetal group joining two neighboring hydroxyl groups. Solketal contains a chiral center on the center carbon of the glycerol backbone, and so can be purchased as either the racemate or as one of the two enantiomers. Solketal has been used extensively in the synthesis of mono-, di ...

Infobox references. 2,3,7,8-Tetrachlorodibenzo-p-dioxin ( TCDD) is a polychlorinated dibenzo -p- dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [ 3] with the chemical formula C 12 H 4 Cl 4 O 2. Pure TCDD is a colorless solid with no distinguishable odor at room temperature.
Infobox references. 4-Amino-3-hydrazino-5-mercapto-1,2,4-triazole is an organic compound with the formula SC 2 N 3 H (NH 2 ) (N 2 H 3 ). The compound consists of a 1,2,4- triazole heterocycle with three functional groups: amine, thioamide and hydrazyl. X-ray crystallography shows that this molecule is polar but with a C=S double bond.
