Chemistry acetylene

For general practical instructions concerning reactions in liquid ammonia one should consult "Preparative Acetylenic Chemistry", Elsevier, Amsterdam, 1971. 

X = Cl, 0-tetrahydropyranyl, 0-CH(CH3)OCjH5 The starting compounds can be easily synthesized by standard procedures in acetylene chemistry.

In 1971 we published "Preparative Acetylenic Chemistry", a collection of procedures for various acetylenic compounds. An important aim of this book was to make acetylenes more accessible, so that barriers for starting research in this field could be lowered. 

Acetylene-Based Routes. Walter Reppe, the father of modem acetylene chemistry, discovered the reaction of nickel carbonyl with acetylene and water or alcohols to give acryUc acid or esters (75,76). This discovery led to several processes which have been in commercial use. The original Reppe reaction requires a stoichiometric ratio of nickel carbonyl to acetylene. The Rohm and Haas modified or semicatalytic process provides 60—80% of the carbon monoxide from a separate carbon monoxide feed and the remainder from nickel carbonyl (77—78). The reactions for the synthesis of ethyl acrylate are... 

With each succeeding year in the 1950s and 1960s there was a swing away from coal and vegetable sources of raw materials towards petroleum. Today such products as terephthalic acid, styrene, benzene, formaldehyde, vinyl acetate and acrylonitrile are produced from petroleum sources. Large industrial concerns that had been built on acetylene chemistry became based on petrochemicals whilst coal tar is no longer an indispensable source of aromatics.

Brandsma L (1971) Preparative acetylenic chemistry, Elsevier, Amsterdam. The first edition contained the preparation of l-phenyl-l,3-butadiyne, but stated ...the compound proved to be very unstable, (and) can be stored at -20°C for a very limited period. This procedure has subsequently been deleted from the second edition (1988).
