Application of Benzyl Salicylate
Benzyl Salicylate, also known as Benzyl o-hydroxybenzoate, is a colorless liquid with amber, musk, floral, ointment and woody aromas. It is used in food flavors such as apricot, peach, plum, banana and pear to enhance the fragrance, and it is also used in cosmetics as a sunscreen additive to protect the skin from ultraviolet rays.
It is used as a fixative in daily flavors such as ylang-ylang, lily-of-the-valley, rosin, jasmine, gardenia, acacia, Suxin, carnation, lilac, and tuberose. It is used in edible flavors such as peaches, raw pears, bananas, apricots, strawberries, and raspberries in very small amounts. Its application examples are as follows:
It is composed of the following according to mass percentage: alcohol made from fermentation and deodorization of corn as the main raw material, deionized water, fruit extract, essence, musk, Benzyl Salicylate and isopropyl myristate; a fruity fragrance perfume The preparation method of the method is to add alcohol obtained by fermenting and deodorizing corn into the reactor, and add musk and Benzyl Salicylate to the container, stir and dissolve, and place it in the dark for a week, and then add deionized water, fruit extracts, and tea extracts to the solution substance, essence and isopropyl myristate, stirred and miscible at -10 ° for 5 hours, then filtered, and the filtered solution was aged for 30 days at a temperature of 20 ° in the aging room, and finally the aged After the final product is filtered and packaged, the perfume preparation is obtained. The advantages are: that is, the alcohol smell of the perfume is suppressed, the fragrance and elegant taste of the perfume are improved, and the fragrance retention effect of the perfume is greatly improved.
Calculated by weight percentage, it consists of 1%-30% osmanthus essence, 5%-55% compound modified oligosaccharides and deionized water; osmanthus essence consists of β-ionone, dihydro-β-ionone, aromatic Camphor Alternative, α-Hexylcinnamaldehyde, α-Amylcinnamaldehyde, Isoamyl Salicylate, Benzyl Salicylate, Benzyl Benzoate, Kara Musk, Citronellol, Geraniol, Cinnamyl Alcohol, Comonac Oil , myristyl aldehyde, thiomenthone, terpineol, methyl anthranilate, osmanthus flower extract, and ethanol with a mass percentage concentration of 1%. The present invention also provides a preparation method of the osmanthus fragrans essence for water-based ink.
The present invention adopts composite modified oligosaccharide as wall material, coats sweet-scented osmanthus essence to form slow-release essence of sweet-scented osmanthus nanocapsules, thereby improving the fragrance retention and water solubility of the essence, making it suitable for adding fragrance to water-based ink. The sweet-scented osmanthus essence used for the water-based ink has delicate and lifelike fragrance, strong natural feeling and long-lasting fragrance.
Calculated by weight percentage, it consists of 1%-30% musk essence, 5%-55% compound modified oligosaccharides and deionized water; musk essence consists of cyclopentadecanolide, musk 105, Jiale musk, Tokyo Musk, Sunflower Musk, Musk T, Ambrox, Cistus Extract, Musk Sunflower Oil, Benzyl Salicylate, Sandalwood 803, Sandalwood 208, Vetiver Oil, Patchouli Oil, Methyl Ionone, Styrax Balm , and the mass percent concentration is 10% indole, geranium oil, coumarin and ethanol.
The present invention also provides the preparation method of the above-mentioned musk essence for water-based ink. The composite modified oligosaccharide is used as the wall material, and the musk essence is coated to form a slow-release essence of musk nanocapsules, thereby improving the fragrance retention and water solubility of the essence. properties, making it suitable for the perfuming of water-based inks. The musk essence for water-based ink obtained by the invention has a transparent, fine and vivid fragrance, and a long-lasting fragrance.
Preparation of Benzyl Salicylate
There are three ways to synthesize Benzyl Salicylate. One is to catalyze the esterification reaction between salicylic acid and benzyl alcohol, and the other is to carry out the esterification exchange reaction between methyl salicylate and benzyl alcohol. The third is the phase transfer catalytic reaction between salicylic acid and benzyl chloride. Although the cost of the three methods is lower, the impurities produced have a greater impact on its aroma.
Under the condition of using polyethylene glycol-400 as a phase transfer catalyst, the product yield is high, but the process is complicated and the operation is inconvenient. Among tetrabutylammonium bromide, triethylbenzylammonium chloride and polyethylene glycol-400 phase transfer catalysts, tetrabutylammonium bromide has the best catalytic effect, and its reaction time is short and easy to operate. industrialization.
Method 1: Add sodium salicylate (0.25mol, 40.2g) and benzyl chloride (0.1mol, 12.6g) to a three-necked round-bottomed flask equipped with a thermometer and a reflux condenser, and add 200mL of N , N-dimethylformamide solvent. The reaction mixture was magnetically stirred and heated to 100°C for reaction. As the reaction progressed, white sodium chloride precipitated out. After the reaction, the precipitate was removed by filtration. The filtrate was first collected by vacuum distillation to collect N,N-dimethylformamide (50°C-51°C/2660Pa) for recycling, and then collected by vacuum distillation to collect Benzyl Salicylate (170°C-172°C/533Pa) 22.43g, yield 98 . 4%.
Method 2: Add a certain amount of benzene, salicylic acid, benzyl alcohol, DCC and DMAP to a dry 250 mL round-bottomed flask, immediately a white flocculent precipitate is formed, and stand at room temperature for 3.5 h. Suction filtration, the filtrate was washed several times with 10% Na2CO3 solution, then washed with saturated NaCl solution until neutral, added a certain amount of anhydrous MgSO4, filtered overnight, recovered benzene by distillation, then rectified under reduced pressure, collected 205 ℃ ~ 208 ℃ / 3465 Pa product is Benzyl Salicylate.
Method 3: A new method for the synthesis of Benzyl Salicylate by solid-liquid phase transfer catalysis: take salicylate, benzyl chloride, catalyst A and catalyst B into the reaction vessel, and react at 80-200°C for 2-20 hours. After the reaction is completed , add water to separate the layers of the reaction solution, separate the organic layer, then wash, dehydrate and distill the organic layer in turn to collect the fraction at 164-165°C/725-735Pa (that is, a pressure value in 725-735Pa The boiling point is 164-165 ℃ fractions) to obtain the product; the catalyst A is a combination of one or more of crown ethers, crown ether derivatives and PEG200-6000; the catalyst B is an alkali metal Halogen salt; the molar ratio of the salicylate to benzyl chloride is 0.8-2:1; the molar ratio of the catalyst A to benzyl chloride is 1-10:100, and the molar ratio of the catalyst B to benzyl chloride The molar ratio is 1-10:1000.
