Xn
Risk Codes:
R22:Harmful if swallowed.
R36/37/38:Irritating to eyes, respiratory system and skin.
Safety Description:
S26: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
S36/37/39:Wear suitable protective clothing, gloves and eye/face protection.

6. Preparation of p-Tolualdehyde
P-Tolualdehyde may be prepared from the Friedel-Crafts formylation of toluene with carbon monoxide and hydrogen chloride under Gattermann-Koch conditions:

7. Use of p-Tolualdehyde
p-Tolualdehyde can be used as organic synthesis intermediates and essence. And it can react with allyl-trimethyl-silane to get 1-p-tolyl-but-3-en-1-ol. This reaction will need reagent dealuminated zeolite-Y exchanged with rare earth metal and solvent nitromethane. The reaction time is 18 hours at reaction temperature of 80 °C. The yield is about 55.0%.
