Benzaldehyde dimethyl acetal - Nature
Open Data Verified Data
colorless liquid. It has a fragrance similar to almond. Found in potatoes. Under acidic conditions, it is easy to hydrolyze to generate benzaldehyde, but it is not affected by alkaline environment. It is stable to oxidant or reducing agent, and the stability is better than that of benzaldehyde.

Benzaldehyde dimethyl acetal - Introduction
It is found in potatoes. Benzaldehyde is easily hydrolyzed under acidic conditions, but it is not affected by alkaline environment. It is stable to oxidants or reducing agents, so it is an important form of preserving benzaldehyde (benzaldehyde is easily oxidized by air, if made into acetal, it is easy to preserve).

Benzaldehyde dimethyl acetal - Safety
Open Data Verified Data
The acute oral LD50 of rats was 0.83-1. 79g/kg. Rabbit percutaneous LD50 >5g/kg. The product was applied to the skin of rabbits for 1 day under closed conditions to produce slight irritation. No irritation was found after two days in the human closed skin contact test with 4% Vaseline formulation.

| Use | Benzaldehyde dimethanol is a liquid with a similar almond fragrance and exists in potato species. It is easy to hydrolyze to generate benzaldehyde under acidic conditions, but it is not affected by alkaline environment. It is an important form of benzaldehyde to preserve the temperature of oxidant or reducing agent. Benzaldehyde dimethanol can be used as a raw material for edible flavors and daily chemical flavors, and can also be used as a reagent for the synthesis of selenium carbonyl compounds. Reagents for the synthesis of selenocarbonyl compounds An effective reagent for constructing selenocarbonyl compounds |
| Preparation | Benzaldehyde dimethanol can be prepared by the dehydration condensation reaction of benzaldehyde and methanol. For spices, it can be used as a green fragrance-floral fragrance component based on lily of the valley or daffodil fragrance, which can have a unique effect. |
