| Introduction | New jasmine aldehyde (English: Helional) is an aromatic organic compound, which can be regarded as a homolog of piperonal, with the structure of phenylaldehydes, Insoluble in water, soluble in alcohol, with a floral aroma, often used in commercial perfumes and odorants. |
| essence and spice | piperyl propionaldehyde is a kind of fresh watermelon fragrance and light lily of the valley and jasmine-like fennel fragrance. it is widely used to prepare a variety of floral, forest and sea breeze flavors such as jasmine and rabbit ear flowers, with lasting fragrance. |
| application | new jasmine aldehyde is a kind of spice widely used in the world. it has gentle floral fragrance like rabbit ear grass. in the formula of cosmetics and soap essence, the dosage is within 20%, the usage is large and the price is high. |
| preparation | 100g of jasmine aldehyde, 100g of methanol, 40g of propionaldehyde, 3g of potassium hydroxide, reaction temperature 40 ℃, reaction time 1.5h, yield 71.4%. In the second step, the hydrogenation of piperonyl propionaldehyde was used to synthesize new jasmine aldehyde. The optimal reaction conditions were determined by single factor method as follows: 100g of piperonyl propionaldehyde, 100g of methanol, 5g of 5% palladium-carbon catalyst, 300KPa of absolute pressure in hydrogenation kettle, 40 ℃ of reaction temperature, 3h of reaction time and 93.1% yield. The two-step total yield is 66.5%. The structural products of the two-step reaction were characterized. Then try to synthesize new jasmine aldehyde by one-pot method, that is, the two-step reaction of synthesis and hydrogenation is completed in a hydrogenation kettle. The optimum reaction conditions were explored by orthogonal method as follows: 100g of jasmonaldehyde, 100g of methanol, 40g of propionaldehyde, 5g of 5% palladium-carbon catalyst, 3g of potassium hydroxide, 300KPa of absolute pressure in hydrogenation kettle, 40 ℃ of reaction temperature, 3h of reaction time and 64.8% yield. |
