Unless I made a sign error I think the best you can do is
$$
\int \frac{d^3\phi}{dx^3} \psi dx + \int \dfrac{d^3\psi}{dx^3} \phi dx = \psi \dfrac{d^2 \phi}{ dx^2} - \dfrac{d\psi}{dx} \dfrac{d \phi}{ dx} + \dfrac{d^2\psi}{dx^2} \phi

##C_2H_5OH+H_2O--->C_2H_6O+H_2O## is wrong.
Ethanol does (partially)dissociate into hydroxyl group and alkyl group, just that this dissociation does not happen in plain water. In nucleophilic substitution reactions (ethanol mainly undergoes SN2) -OH of ethanol is partially dissociated from...
From the aforementioned book :
The prerequisites for this presentations are (1) familiarity with Hilbert-space formalism of quantum mechanics (2) assimilation of basic principles of special relativity (3) a goodly measure of mathematical maturity
