pyromucic, a. Chem.|paɪərəʊˈmjuːsɪk|
[f. pyro- 3 + mucic: cf. F. pyromucique substituted for pyromuqueux (De Morveau and Lavoisier 1787).]
In pyromucic acid, an acid, C5H4O3, metameric with pyromeconic acid, produced by the dry distillation of mucic acid, and occurring in white glistening scales or needles. So pyromucic alcohol, pyromucic chloride, pyromucic ether, etc.
1794G. Pearson tr. De Morveau, etc. Table Chem. Nom. 22 Radical Pyro-mucic. 1819J. G. Children Chem. Anal. 284 Pyromucic acid has been lately discovered by M. Hontou Labillardière. 1836–41Brande Chem. (ed. 5) 1072 When mucic acid is subjected to destructive distillation it yields..pyromucic acid.
Hence pyroˈmucamide, an amide of pyromucic acid, C5H5NO2; pyromucic dipyromucamide, C5H6N2O; pyroˈmucate, a salt of pyromucic acid; pyroˈmucyl, the radical C5H3O2 of pyromucic acid; also † pyromucous a. = pyromucic, † pyromucite = pyromucate.
