Reactions in which Antipyonin is involved

  • Na2B4O7 + H2SO4 + 5H2O = Na2SO4 + 4H3BO3
  • 4BCl3 + 14{M}OH -> {M}2B4O7 + 12{M}Cl + 7H2O , where M = Na K
  • Na2B4O7 + 2NaOH "700^oC"--> 4NaBO2 + H2O
  • 4NaBO2 + H2O "100^oC"--> Na2B4O7 + 2NaOH
  • 2{M}OH + 4H3BO3 -> {M}2B4O7 + 7H2O , where M = Na K Li
