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%.
