Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol , with its formula also written as C 2 H 5 OH , C 2 H 6 O or EtOH, where Et stands for ethyl .
The acute toxicity of 1-butanol is relatively low, with oral LD 50 values of 790–4,360 mg/kg (rat; comparable values for ethanol are 7,000–15,000 mg/kg). [ 8 ] [ 32 ] [ 11 ] It is metabolized completely in vertebrates in a manner similar to ethanol : alcohol dehydrogenase converts 1-butanol to butyraldehyde ; this is then converted to ...
Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2, and thus ethyl acetate is likely to be a good solvent. Nylon 6,6 has a solubility parameter of 13.7 cal 1/2 cm −3/2 , and ethanol is likely to be the best solvent of those tabulated.
The ideal gas equation can be rearranged to give an expression for the molar volume of an ideal gas: = = Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is based on the gas constant: R = 8.314 462 618 153 24 m 3 ⋅Pa⋅K −1 ⋅mol −1, or about 8.205 736 608 095 96 × 10 −5 m 3 ⋅atm⋅K ...
The number of millilitres of pure ethanol is the mass of the ethanol divided by its density at 20 °C (68 °F), which is 0.78945 g/mL (0.82353 oz/US fl oz; 0.79122 oz/imp fl oz; 0.45633 oz/cu in). [4] The alc/vol standard is used worldwide.
Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol.This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises: [9] Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%.
