Web1 Introduction Ethane-1,2-diol (IUPAC name) also known as 1,2-ethanediol, ethylene glycol, monoethylene glycol, or 1,2-dihydroxyethane, CAS 107-21-1, C 2 H 6 O 2, is a very common heat-transfer fluid. Nevertheless, reference correlations for its viscosity and its thermal conductivity do not exist, and the current formulations WebIf there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) The N position indicator for amines and amides comes before "1", e.g., CH 3 CH(CH 3)CH 2 NH(CH 3) is N,2-dimethylpropanamine. WebEthane-1,2-diol, (ethylene glycol, monoethylene glycol, MEG) which is manufactured from ethene via epoxyethane, is used to make polyester fibres, resins and films although it is probably better known for its use as … st lawrence university party scene
