    = 2BrAg + (C„H30.0).,C„H4. By distilling acetate of etheue with Bii(OII), = (C2H3bO)2Ba + C..,H,(OH),,. Potassium may expel oue or two atoms of H in OH, and yield moii- or di-etheiiate. Ethers of the glycols obtained by treatment with iodmethane. iodethane, &c. Thus: CoH,,(OH)(ONa)+ C.HjI = INa + ETHYL ETUENATE C.U^COHXOCJIJ. Again : CoH.|(ONa)., + ^CjHsI = 2lNii = diethyl ethenate CJi., (OCotI,),. irlydroxyl-acids produce ethereal salts, but the hydr- acids of CI, Br, I, &c., only remove ono atom of Oil, forming ethene chlorhydrate C.,H,0H.C1. Dichlorinaied etheu CoH.,CI., can only be produced from the alcohol by 2CI5P - 2CIH + 2POCI3 + ethene dichlorhje U„HjC1o, the Dutch liquid of Chemistry. C.H^Clo is a thin colorless liquid, of ethereal odor ; heavier than water. Boils at 82°. 3 C. Prepared by mixing CL with CjH^. Gfil^ is a white crystalline, arumatie substance, the analogue of ethane CjHf/. C„C1„ in white nei dies, obtained by passing CHCI3 or CoCl^ through a red-hot tube. ETHENEBEOiinDE (C,Hj)Br2, boilsiit i29°.5 C. Ethene Iodide C.jH^L, a crystalline substance, made by acting upon C^lifi]„ with I2. Ethane cyanide (C,H,)Cvo, crystalline, melts a't 50° C. By distilling 2CNK + C,H,Br„ = 2BrK + Cy^CCjHj). Ethene oxide (C^H.,)©, transparent, colorless fluid; boils at 13°.5 C It takes up nascent H,, and becomes elhyl-alcohol. From ethene chlor-iiydrin CjHiOHCi + HOK = (JIK + OH, + ethene oxide CjH/). It is a powerful base, and unites with H3N to form basic compounds with i, 2, 3 and 4 molecules of CjH^, of syrupy character and no crystalline compounds with acid sulphites. Ethene oxide is thus distin- guished from aldehyde or ethidine oxide CH3COH. Ethene SULph-hydrate C2H.,(SH)2, colorless oil, insoluble in water. From C^HiBi-jby 2SHK. Ethene sulphide (C2Hj)S,(C2ll4)S. Crystalline solid. Vapor-density 60. Ethene sulphonic acid CjHiCSOsH),, diificult to crystallize. By oxydation of the sulph-hydrate of ethene. or by boiling ethyl-alcohol with sul- phuric anhydride. CjH,(0H)S03H is isethionic acid, and isomeric with ethyl sllphdric acid C2H5HSO4. Uncrystallizable liquid, decomposed by boiling with water. Ammonium isethionate CjH.OHSOjH.N, heated to 230° C, into OIL and ethene- amido-sulphonic acid or Taurine C2H,,(H2N)S03H. Isetliionic aoid, by oxydation of the sulph-liy(Irate of ethene, or by action of nitrous aciil on taurine - 'N^ + OH, -f isethionic arid (C2H,)(OH)S03H. Taurine C2H4(H2N)S03H is found in tlic bile of oxen, &c , in coinbinatien with cholie acid, and is pri'jiared by boiling TAuiiOcuouc acid C2(,H,,5In SO, -1- OH2 with IIOK. In rhombic prisms, easily soluble. Ethionic axuyduide CjH4(S03)„ in deliquescent needh/s. H
