Ethylate sentence example

ethylate
  • It is a most important synthetic reagent; with sodium or sodium ethylate it forms sodio-malonic ester, which reacts readily with alkyl halides, forming alkyl malonic esters, which are again capable of forming sodium derivatives, that by further treatment with alkyl halides yield the di-alkyl malonic esters.

  • Many diketo compounds suffer condensation between two molecules to form hydrobenzene derivatives; thus a, 7 -di-acetoglutaric ester, C 2 H S O 2 C(CH 3 CO) CH CH 2 CH(CO CH 3)CO 2 C 2 H 5, yields a methylketohexamethylene,whiles-acetobutyric ester,CH 3 CO (CH2)2C02C2N5, is converted into dihydroresorcinol or m-diketohexamethylene by sodium ethylate; this last reaction is reversed by baryta (see Decompositions of Benzene Ring).
