What is Octyl Acetate?

Octyl acetate is a colorless slightly white liquid. Octyl acetate is a colorless transparent liquid that exists in natural citrus and green tea essential oils, commonly known as “citrus essence”. Octyl acetate has fruity aromas such as apple, tangerine, and peach, and floral aromas such as orange and jasmine. It is mainly used as food flavor, widely used in food, beverage and cosmetics; it 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 many disadvantages of the sulfuric acid catalytic process, the development of environmentally friendly catalysts and green processes has become a research hotspot. Among them, strongly acidic cation exchange resin is a kind of catalyst which not only has industrial application prospect, but also is suitable for perfume synthesis industry.

Octyl Acetate Uses

  1. Octyl acetate is typically used in small amounts for jasmine, gardenia, pleasant orange bloom, citrus, and also iris scents. It is additionally used in a small amount for food tastes such as raspberry, strawberry, cherry, apple, lemon, peach, raw pear, and brandy.
  2. Octyl acetate is a flavoring that is allowed to be utilized according to GB 2760– 1996. It is primarily made use of to prepare peach, strawberry, raspberry, cherry, apple and also lemon, citrus and other tastes.
  3. Octyl acetate was used as solvent. The item has orange, jasmine and peach-like fragrance, as well as the all-natural item exists in bitter orange, eco-friendly tea, etc.

Applications of Octyl Acetate

Octyl acetate has the aroma of orange, jasmine and peach, and is mainly used in the formulation of food flavors to prepare floral and fruity flavors, and can also be used as a solvent for resins and paints. Its application examples are as follows:

1. Prepare a water-based ink with grapefruit essence, calculated by weight percentage, composed of 1%-30% grapefruit essence, 5%-55% composite modified oligosaccharides and deionized water; Pomelo essence is composed of grapefruit oil, grapefruit ketone, sweet orange oil, lemon oil, tangerine oil, capric aldehyde, octanal, ethyl butyrate, octyl acetate, linalool, linalyl acetate, terpineol, Composed of terpineol acetate and ethanol, the above-mentioned preparation method of grapefruit essence for water-based ink adopts composite modified oligosaccharides as wall material, and grapefruit essence is coated to form grapefruit nanocapsule slow-release essence, thereby improving The fragrance retention and water solubility of the essence make it suitable for the fragrance of water-based inks. The grapefruit essence for water-based ink obtained by the invention has fresh, transparent, lifelike, strong natural feeling and long-lasting fragrance.

2. Prepare a kind of environment-friendly water-based colorful coating, comprise and make by the composition of following parts 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 parts -35 parts of fluorosilicone emulsion, 5-10 parts of talc, 15-25 parts of curing agent, 10-15 parts of defoamer, 15-20 parts of tricresyl phosphate, 10-15 parts of hydroxyethyl cellulose and 1- 3 parts sodium benzoate. A kind of environment-friendly water-based colorful coating of the present invention, coating film is bright in color, and decorative effect is good; Through reasonable proportioning, the type and dosage of ultraviolet absorber and flame retardant suitable for coating are optimized, and the artificial weather aging resistance is improved. Excellent fire resistance, corrosion resistance and stability, high bonding strength, no peeling, no cracks, safe and non-toxic, short curing time, convenient construction and high efficiency.

3. Prepare a scale inhibitor 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 group methylene phosphonic acid, octyl acetate, acryl alcohol, melamine and dimethyl sulfoxide; the products are mainly used in heat exchange equipment to prolong the life of heat exchange equipment pipelines, and the corrosion inhibition rate is 97-99.9% %, does not contain chromate and nitrite; it has a good protective effect on carbon steel, stainless steel, and steel alloy, and is suitable for desalinated water, softened water, and deionized water systems; it has long drug effect time, strong scale inhibition ability, and corrosion inhibition effect Good, the operating concentration is 25-45×10-6, and it is also suitable for closed circulating cooling water systems; the effect is long-lasting, it will not degrade for a long time, it is non-toxic and harmless, and it can be placed at 50-60°C for 3-9 months, and the scale inhibition effect is 98 -99%.

Preparation of Octyl Acetate

Method 1: Add metered octanol and acetic acid into a 250 mL four-neck flask equipped with a stirrer, a gas phase condenser, and a liquid phase thermometer, stir and heat, and when the reaction liquid reaches the specified temperature, take a sample to measure the initial acid value of the reaction liquid At the same time, add the metered catalyst NKC-9 into the four-necked flask, start timing, and take samples at regular intervals to determine the acid value. The reflux reaction ends after a certain period of time in a state of boiling or slight boiling. 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 saline, saturated sodium carbonate solution and saturated saline, dried over anhydrous magnesium sulfate, and distilled under normal pressure to collect fractions at 208-210°C to obtain octyl acetate as a colorless transparent liquid.

Method 2: take p-toluenesulfonate copper as catalyst, without solvent, the esterification reaction between acetic acid and n-octanol is studied, and the molar ratio of alkyd substance, catalyst consumption, reaction time are investigated on the recovery of octyl acetate. rate impact. Result shows, p-toluene sulfonate copper has good catalytic activity, in n-octanol consumption 0.1 mol, n (n-octanol): n (acetic acid)=1: 2.5, catalyst consumption is 0.75% of reactant total mass, reflux Under the condition of reaction for 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 copper oxide and 0.2 mol p-toluenesulfonic acid

In a 250 mL round bottom 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: the synthesis of octyl acetate: in a 100 mL round bottom flask, add acetic acid,

Put n-octanol and a certain amount of catalyst into a collector-type constant-temperature heating magnetic stirrer, install a reflux condenser, start the stirrer, heat and reflux for a certain period of time, stop heating, cool slightly, separate and recover the catalyst, and the reaction solution Wash with saturated brine first, then neutralize with saturated sodium bicarbonate solution, dry over anhydrous magnesium sulfate and distill, collect fractions at 206-210 °C, weigh and calculate the yield of octyl acetate, and measure the refractive index and infrared spectrum.
