What is Octyl Acetate?

Octyl Acetate is a colorless, whitish liquid. Octyl acetate is a colorless and transparent liquid that exists in the essential oils of natural citrus and green tea leaves, commonly known as “citrus flavor”. Octyl Acetate has fruit aromas such as apple, tangerine, peach, and floral aromas such as orange and jasmine. Mainly used as food flavor, widely used in food, beverage, cosmetics; can also be used as solvent, internal plasticizer, etc. Industrially, Octyl Acetate is obtained by direct esterification of acetic acid and n-octanol under the catalysis of concentrated sulfuric acid. Due to the disadvantages of sulfuric acid catalytic process, the development of environmentally friendly catalysts and green processes has become a research hotspot. Among them, the strong acid cation exchange resin is a kind of catalyst with industrial application prospect and suitable for perfume synthesis industry.

Octyl Acetate Uses

  1. Octyl Acetate is often used in small amounts in jasmine, gardenia, orange blossom, citrus, and iris scents. It is also used in small amounts in edible flavors such as rubus, strawberries, cherries, apples, lemons, peaches, raw pears, and brandy.
  2. Octyl Acetate is GB 2760–1996 stipulates that the edible spice is allowed to be used. Mainly used to prepare peach, strawberry, raspberry, cherry, apple and lemon, citrus and other flavors.
  3. Octyl Acetate was used as solvent. The product has orange, jasmine and peach-like aroma, natural products exist in bitter orange, green tea, etc.

Octyl Acetate Application

Octyl Acetate has orange, jasmine and peach-like aromas. It is generally utilized in food taste solutions to prepare blossom as well as fruit flavors, and also can additionally be utilized as a solvent for resins and also finishings. Examples of its application are as adheres to:

1. Prepare a kind of grapefruit essence for water-based ink, determined by weight percent, by 1%-30% grapefruit significance, 5%-55% compound changed oligosaccharide and also deionized water; Grapefruit essence is composed of grapefruit oil, grapefruit ketone, sweet orange oil, lemon oil, tangerine oil, decanal, octanal, ethyl butyrate, octyl acetate, linalool, linalyl acetate, terpineol, Made up of terpineol acetate as well as ethanol, those preparation approach of grapefruit essence for water-based ink takes on composite customized oligosaccharide as wall product, and also the grapefruit essence is coated to form grapefruit nanocapsule slow-release essence, consequently improving the The scent retention and water solubility important make it suitable for perfuming water-based inks. The grapefruit significance for water-based ink acquired by the creation has fresh scent, passing through hair, lifelikeness, strong natural feeling and also long lasting fragrance.

2. Preparation of an environmentally friendly water-based colorful paint, comprising the adhering to components by weight: 80-90 parts of polyvinyl chloride, 25-30 parts of nitrocellulose, 25-35 parts of Octyl Acetate, 3-5 parts of propylene glycol, 30- 35 components fluorosilicone emulsion, 5-10 parts talc, 15-25 components healing agent, 10-15 components defoamer, 15-20 components tricresyl phosphate, 10-15 parts hydroxyethyl cellulose and also 1-3 parts of sodium benzoate. The environment-friendly water-based vibrant paint of the creation has bright color as well as excellent decorative impact of the finishing film; with a reasonable percentage, the kinds as well as quantities of ultraviolet absorbers as well as fire resistants suitable for the paint are optimized, and also the fabricated weathering resistance is enhanced, as well as the anti-aging homes are boosted. Superb fire resistance, rust resistance and security, high bonding strength, no peeling, no splits, safe and also safe, short curing time, practical building and also high efficiency.

3. Prepare a range prevention for heat exchange equipment, the raw materials are sodium tripolyphosphate, maleic anhydride, sodium pentaerythritol phosphate, benzothiazole, water, zinc tungstate, tannic acid, phosphoric acid, pentaerythritol phosphate, allyl Glyceryl ether, polyaminopolyether-based methylene phosphonic acid, Octyl Acetate, allyl alcohol, melamine and dimethyl sulfoxide; the items are mostly used in warmth exchange tools to prolong the life of warmth exchange equipment pipelines, and also the rust inhibition price is 97-99.9%, without chromate and also nitrite; great security impact on carbon steel, stainless-steel, steel alloy, appropriate for desalinated water, softened water, deionized water supply; long medication effect time, strong scale inhibition ability, good deterioration restraint result, operating focus 25-45 × 10-6, also ideal for shut flowing cooling water system; durable result, no deterioration for a long period of time, non-toxic and harmless, placed at 50-60 ℃ for 3-9 months, the anti-scaling effect is 98- 99%.

Preparation of Octyl Acetate

Method 1: Add metered octanol and acetic acid to a 250 mL four-necked flask with a stirrer, a gas phase condenser and a liquid phase thermometer, stir and heat, and when the reaction solution reaches the specified temperature, take a sample to measure the initial acid value of the reaction solution , at the same time, add a metered amount of catalyst NKC-9 to the four-necked flask, start timing, and measure the acid value by sampling at regular intervals. The reaction is completed by refluxing for a certain period of time in a boiling or slightly boiling state. Cool, weigh, filter out the catalyst, measure the acid value of the reaction solution and calculate the conversion rate of octanol. The filtrate was washed successively with saturated brine, saturated sodium carbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and the fractions at 208-210 °C were collected by atmospheric distillation to obtain Octyl Acetate, a colorless transparent liquid.

Method 2: The esterification reaction between acetic acid and n-octanol was studied by using copper p-toluenesulfonate as catalyst without solvent. The effect of alkyd substance ratio, catalyst dosage and reaction time on the yield of Octyl Acetate was investigated. Impact. The results show that copper p-toluenesulfonate has good catalytic activity. When the amount of n-octanol is 0.1 mol, n(n-octanol):n(acetic acid)=1:2.5, the amount of catalyst is 0.75% of the total mass of the reactants. Under the reaction conditions of 50 min, the yield of octyl acetate can reach 88.5%, and the catalyst still maintains high activity after repeated use for 5 times.

Step 1: Synthesis of copper p-toluenesulfonate: take 0.15 mol of copper oxide and 0.2 mol of p-toluenesulfonic acid

In a 250 mL round-bottomed flask, add 150 mL of deionized water, react at reflux temperature for 4 h, cool, and filter; concentrate the filtrate until a blue crystal film appears, crystallize, and dry; then recrystallize with 95% ethanol After drying in a vacuum drying oven to constant weight, copper p-toluenesulfonate crystals can be obtained. The crystal does not absorb moisture and is convenient to use and store.

Step 2: Synthesis of Octyl Acetate: In a 100 mL round-bottomed flask, add acetic acid,

n-Octanol and a certain amount of catalyst are put into a collector-type constant temperature heating magnetic stirrer, a reflux condenser is installed, the stirrer is started, and after heating and refluxing for a certain period of time, the heating is stopped, and the reaction solution is cooled slightly, and the catalyst is separated and recovered. First washed with saturated brine, then neutralized with saturated sodium bicarbonate solution, dried over anhydrous magnesium sulfate and then distilled, collected fractions at 206-210 °C, weighed to calculate the yield of Octyl Acetate, and determined the refractive index and infrared spectrum of the product.
