Web313: Triethylamine CAS-No. 121-44-8 Revision Date 2007-07-01 SARA 311/312 Hazards: Fire Hazard, Acute Health Hazard, Chronic Health Hazard 16. Other Information Revision B, June 2015 The information contained herein is provided in good faith and is believed to be correct as of the date hereof. WebEthyl alcohol and its aqueous, solutions form useful standard liquids for testing viscometers, within the range of viscosities obtainable. A mixture of 45 per cent. by volume of ethyl alcohol and water has a viscosity which is almost exactly four times that of water at 0°. Since the viscosity of alcohol -water mixtures passes through a maximum ... WebCommon bases are triethylamine, Et 3 N, or pyridine, C 6 H 5 N. In each case the -OH reacts first as a nucleophile, attacking the electrophilic center of the halogenating agent. A displaced halide ion then completes the substitution displacing the leaving group. Note that it is not-OH that leaves, but a much better leaving group (e.g. SO 2) focusrite scarlett 2i2 software compatibility
