The heat of hydrolysis of dimethoxychloroborane has been measured; for the reaction, ( CH 3 O ) 2 BCl ( liq ) + 3 H 2 O ( liq ) = H 3 BO 3 ( c ) + 2 CH 3 OH ( liq ) + HCl ( g ) Δ H ( 25 ° C ) = - 26.6 ± 0.8 kj / mole = - 6.4 ± 0.2 kcal / mole . From this, we have calculated the heat of formation of dimethoxychloroborane: for the liquid, Δ Hf ° (25 °C) = -782.1 ± 1.8 kj/mole (-186.9±0.4 kcal/mole), and for the gas, Δ Hf ° (25 °C) = -747.9 ±2.2 kj/mole (-178.8±0.5 kcal/mole). |
