| Introduction | terpineal acetate naturally exists in a variety of essential oils, such as cedar oil, pine needle oil, melaleuca oil, Cardamom oil, etc. It is a colorless to yellowish liquid with lemon and lavender aroma. It is industrially prepared by acetylation of terpineol with acetic anhydride catalyzed by sulfuric acid at slightly higher than room temperature. |
| Application | terpineyl acetate can be used as a preparation of peach, plum, apricot, raspberry, cherry, round grapefruit, medium to, sage, cardamom, spices and citrus and other food flavors (ADI: 1 mg/kg per day, in China according to the implementation of GB2760-1996 standards); Can also be used as lavender, lemon, forest, Fu Qi and other fragrance. |
| assay | was determined by method one in the ester determination method (OT-18). The amount of the sample taken was 1G. Reflux time was changed to 4H. The equivalence factor (e) in the calculation is taken as 98.15. Or according to Gas chromatography (GT-10-4) using non-polar column method. The values measured according to FCC regulations are the sum of the two isomers. |
| toxicity | GRAS(FEMA). Ld504160 mg/kg (rat, oral). |
| usage limit | FEMA(mg/kg): Soft drink 3.5; Cold drink 3.2; Candy 6.3; Baked goods 15; pectin 14~260; Condiment 15; Meat 1.7~40. Moderate limits (FDA § 172.515,2000). |
| Use | is used for mixing lavender, Gulong perfume, terpinyl acetate is the food flavor permitted by the hygienic standard for the use of food additives in China. It is used in the preparation of bayberry, cherry, citrus, peach, spices and other fruit-based food flavors. The dosage of chewing gum is 14 ~ 260mg/kg; 1.7 ~ 40mg/kg in meat; 15mg/kg in condiment; 15mg/kg in baked food; 6.3mg/kg in candy; 3.5 mg/kg in soft drinks; 3.2 mg/kg in cold drinks. It is one of the flavors of lemon oil, lavender oil and orange leaf oil. Due to the low price, commonly used in lavender, Dragon, vanilla, pine needles, spices, citrus flavor, can be used for soap flavor. Can also be used for food flavors, such as berries, lime, orange, cherry, peach, plum, apricot, spice, meat and so on. It is also used in cardamom, thyme and other flavoring essential oils to enhance the fragrance. GB 2760-1996 provides for the permitted use of flavorants. Mainly used in the preparation of peach, plum, apricot, raspberry, cherry, round pomelo, to, sage, cardamom, spices and citrus flavor. |
| production method | at room temperature, add a mixture of acetic acid, sulfuric acid and water to turpentine, the mixture was maintained at 45 to 50 ° C. During mixing, and then allowed to stand at 30 to 40 ° C. For several hours. Water was added to precipitate the oil layer, separated, neutralized with sodium carbonate solution, and then subjected to vacuum distillation to remove impurities. It is obtained from the reaction of terpineol with acetic anhydride and anhydrous sodium acetate. Terpineol is reacted with acetic anhydride and anhydrous sodium acetate, the reactant is neutralized with alkali, washed with water, separated and dried, and then distilled under reduced pressure to obtain a finished product. Turpentine is used as a raw material: a mixed aqueous solution of sulfuric acid and acetic acid is added to turpentine, the temperature is maintained at 45 to 50 ° C. During mixing, and then the mixture is left at 30 to 40 ° C. For several hours. Water is added to precipitate the oil layer, which is neutralized with sodium carbonate solution after separation, and then the product is obtained by vacuum distillation. |
