(7) From (8), it is evident that an error is induced at every time-step due to the truncation of the Taylor series, this is referred to as the local truncation error (LTE) of the method. For the forward Euler method, the LTE is O(h2). Hence, the method is referred to as a first order technique.
Product Description: 19041 HEXANE CITGO'S Hexane is a low-boiling aliphatic solvent consisting primarilyof C6 saturated hydrocarbons. Hexane is a clear, colorless, flammableliquid miscible with most common organic solvents and has a lightaliphatic odor.
Best Answer: Petroleum ether is a mixture of two hydrocarbons, Hexane which is liquid and a certain amount of Propane, which is a hydrocarbon gas soluble in Hexane.This lowers the boiling point of the mix below that of Hexane. believe it is about 30 dollars a gallon. FYI: Petroleum ether is not an actual ether. Diethyl ether is a true ether and is much more volitile and an even better oil extraction solvent. However it is also twice as inflammable and can even decompose into explosive peroxides as it ages.
