MBEO 1.8 Adduct. [Air Prods.] Ethoxy-laied acetylenic alcohol corrosion inhibitor, levder, brightener to dectro-plating. [Pg.226]

Sodamide in liquid ammonia is a particularly suitable reagent for preparation of alkoxyacetylenes, e.g., methoxy-, ethoxy-, and butoxy-acetylene, from dialkyl chloroacetals 194 both hydrogen halide and the alcohol are split off in this process ... [Pg.839]

Dehydrative Condensation of Carboxylic Acids with Amines and Alcohols. For reversible fluorescent labeling of amino groups, ethoxy(trimethylsilyl)acetylene was used as a dehydrating reagent to couple dansylaminomethylmaleic acid (DAM) with benzylamine through a maleic anhydride intermediate (eq 6). ...
