Application
1. It is the main spice in Hawthorn flower, sunflower and lilac flavor.
2. It is used as a fragrance agent in lily of the valley.
3. It is used as a modifier in Osmanthus fragrans.
4. It can also be used in daily flavors and food flavors.
Property
It is soluble in ethanol, soluble in ethyl ether, benzene and other organic solvents, also soluble in water.
Storage
Stored at a dry, shady, ventilated place.
Stability
1. Its gas and air form an explosive mixture. Wear protective glasses, protective clothing, and protective gloves.
2. Exist in tobacco leaves and smoke.
3. It naturally exists in essential oils such as star anise oil, cumin oil, star anise oil, dill oil, acacia oil, and corn oil.
4. It is not very stable to light, it is easy to oxidize and change color in the air to generate anisic acid.
5. p-Methoxybenzaldehyde can be used to protect diols, dithiols, amines, hydroxylamines and diamines.
Diol protection p-methoxybenzaldehyde can be easily formed by the reaction of diol and aldehyde to form acetal. The catalyst used can be hydrochloric acid or zinc chloride, or other methods such as iodine catalysis and polyaniline as the carrier Sulfuric acid catalysis, indium trichloride catalysis, bismuth nitrate catalysis, etc. P-methoxybenzaldehyde reacts with L-cysteine to obtain thiazole derivatives.
Reaction with amino groups P-methoxybenzaldehyde can react with amino groups to form Schiff bases, which are reduced by NaBH4 to form secondary amines.
Formation of ethylene oxide derivatives p-methoxybenzaldehyde can react with sulphur ylides to form ethylene oxide derivatives, and can also react with diazonium compounds to obtain such derivatives. Reaction with ethylene oxide derivatives can also expand the ring to obtain furan ring derivatives.
Diacylation reaction Under the catalysis of tetrabutylammonium bromide (TBATB), p-methoxybenzaldehyde can react with acid anhydride to form diacylation products.
In the allylation reaction, due to the strong electron donating effect of the para-methoxy group, p-methoxybenzaldehyde reacts with allyltrimethylsilane under the catalysis of bismuth trifluorosulfonate to obtain the diallylated product .
