What is Terpineol?

Terpineol has an ache and clove-like fragrance. Appearance is thick liquid, but tends to crystallize quickly, boiling point 218 ~ 219 ℃, 85 ℃/ 400Pa, melting point 35 ℃ (α-terpineol). Mostly made use of in the prep work of lilac, lily of the valley, acacia, orange blossom as well as other fragrant soaps and also cosmetic significances. Pure α-terpineol can still be made use of to prepare edible tastes such as lemon, orange and also peach. Several ester substances prepared from terpineol as resources are also outstanding scents.
Terpineol, also referred to as sycamore oil and turpentine terpene alcohol, naturally exists in necessary oils such as want oil, lavender oil, jalapeño oil, orange fallen leave oil, as well as neroli oil. A type of scent acquired by hydration of ene or β-pinene to develop hydrated terpene diol, dehydration and fractionation. Terpineol is just one of the earliest artificial scents to accomplish commercial manufacturing, mainly utilized as soap significance, and also has a history of greater than 100 years. Terpineol is a mass flavor item with a yearly outcome of several thousand lots in the world. It is extensively utilized in different everyday chemical fragrance solutions, particularly in fragrance solutions for soaps and synthetic cleaning agents, and also the dosage can get to 30%. IFRA has no constraints.

Terpineol Uses

  1. Terpineol product is a mixture of various isomers mainly composed of α-terpineol, β-terpineol and γ-terpineol. Terpineol has a lilac aroma and is a green and environmentally friendly fine chemical product with a wide range of uses. It is often used as an industrial solvent, bactericide, cleaning agent, mineral flotation agent, blending essence, etc. It can be used in medicine, household and daily cleaning agents and cleaning agents, inks, instruments, telecommunications and other industries.
  2. Terpineol is separated right into 2 types: taste requirements and also medical specification. At the same time, it is utilized as a fresh breath agent; as a body fragrance, it is frequently utilized in lily, lavender, lily-of-the-valley, acacia, herbaceous rhinoceros, orange blossom and also various other flavors, and also is additionally a crucial flavor in magnolia, gardenia, narcissus as well as pine needle-type flavors. Terpineol is reduced in cost as well as is widely used in mixing soap and aesthetic scents and state-of-the-art scents similar to lavender fragrance, as well as in pharmaceutical, electrical, ink and other markets.

Preparation of Terpineol

The first step is to synthesize hydrated terpene diol: mix 272g of industrial grade turpentine or one of α-pinene or β-pinene with acid water with an acid mass fraction of 20-75% and put it into the reactor, Wherein the acid-water mixture is made of one or two or more of sulfuric acid, phosphoric acid, p-toluenesulfonic acid, and chloroacetic acid mixed with water to form a catalyst, and polyvinyl alcohol, organic One or more of the amine salts are used as emulsifiers, and the hydration reaction is carried out under stirring conditions of 100 to 1000 rpm (preferably 400 to 800 rpm) to generate crystalline hydrated terpene glycol, and ultrasonic waves are used in the initial 2 to 4 hours of the reaction. Assisted emulsification. The mass of water is 1-3 times, preferably 1-2 times, the mass of turpentine; the mass of the catalyst is 20-75%, preferably 25-50% of the mass of the turpentine; the mass of the emulsifier is 0.001-0.2% of the mass of the turpentine , preferably 0.01-0.1%; the reaction temperature is 20-75°C, preferably 20-60°C; the reaction time is 12-36h, preferably 18-24h. Turpentine is one or more mixtures of gum turpentine, sulfate turpentine, or wood turpentine and dry distillation turpentine. Industrial grade α-pinene or β-pinene and α-pinene or β-pinene derived from other natural essential oils (such as eucalyptus oil, camphor oil, etc.) are used as reaction raw materials instead of turpentine.

In the second step, the stirring is stopped after the hydration reaction is completed, and ultrasonic waves are used to vibrate and stir for a certain period of time, and then the acid-water mixture containing a small amount of hydrated terpene glycol is released from the bottom of the reactor after sedimentation and stratification, and the acid-water mixture after further clarification is formulated After reaching an appropriate proportion, all of them are recovered for the next reaction.

In the third step, the crystalline product left in the reactor is neutralized and washed once with an aqueous NaOH solution with a mass fraction of 3 to 5%. During the washing process, the acid catalyst remaining between the crystals is fully obtained by ultrasonic strengthening. After the recovery of the alkaline washing solution, an appropriate amount of NaOH can be added to prepare an aqueous solution with a mass fraction of 5% for the next batch of neutralization and washing.

In the fourth step, the crystalline product after alkali neutralization and washing is washed with water under the action of ultrasonic strengthening until the washing liquid is neutral and weakly alkaline. The washing liquid is released, and the washing liquid obtained by each recovery is used for the washing of the next batch of reaction products, and the washing water that cannot be reused is put into the neutralization tank for clarification and then recycled.

The 5th step, dehydration of terpene glycol to synthesize terpineol: the hydrated terpene glycol crystalline product obtained through neutralization and water washing and the unseparated red oil contained therein are transferred into the dehydration reactor under the action of adding water and stirring, with One or a mixture of two or more of the commonly used inorganic or organic acids such as sulfuric acid, phosphoric acid, p-toluenesulfonic acid and chloroacetic acid are used as catalysts, and the hydration terpene glycol is accelerated in the aqueous medium with ultrasonic assistance within 1 hour after the material is added. Dispersing and dissolving in the terpene glycol, the dehydration reaction of terpene glycol is carried out to generate the crude product of terpineol commonly known as butter. During the dehydration reaction, the mass of water is 1 to 2 times, preferably 1 to 1.5 times, the mass of the hydrated terpene diol and the red oil; the mass of the catalyst is 0.1 to 2.5% of the mass of the hydrated terpene diol and the red oil, preferably 0.1 ~1.0%; the reaction temperature is 60-120° C., preferably 80-110° C.; the reaction time is 2-12 h, preferably 3-6 h.

The sixth step, separating and refining terpineol: after the hydration reaction and the dehydration reaction are completed, stand to separate out the lower acid liquid layer. The obtained crude terpineol product of the upper layer oil, namely butter, is neutralized with an aqueous sodium hydroxide solution with a mass fraction of 2-10% and washed with water until the washing solution is neutral and slightly alkaline (pH=7-9), The crude product is obtained by standing for stratification, and then through vacuum distillation and continuous rectification to obtain a terpineol product that meets the standard.

Physicochemical Properties of Terpineol

Terpineol has 3 isomers, α, β, as well as γ. According to their melting points, they ought to all be strong, yet the synthetic items sold on the market are mainly liquid mixes of these three isomers.
Alpha-terpineol is offered in 3 kinds: dextrorotatory, levorotatory and also racemic. D-alpha-terpineol is normally existing in cardamom oil, sweet orange oil, orange leaf oil, neroli oil, jasmine oil, nutmeg oil; L-alpha-terpineol is normally present in yearn needle oil, camphor oil, cinnamon oil In fallen leave oil, lemon oil, white lemon oil, rosewood oil. Beta-terpineol has cis as well as trans isomers (uncommon in crucial oils). Gamma-terpineol is present in juniper oil in free or ester form.
Alpha-terpineol-based blends are made use of in scents. It is an anemic thick liquid. Has an one-of-a-kind clove scent. The boiling point is 214 ~ 224 ℃, and also the family member thickness is d25250.930 ~ 0.936. Refractive index nD201.482 ~ 1.485. Insoluble in water, soluble in organic solvents such as ethanol and propylene glycol. Alpha-terpineol is present in greater than 150 plant leaves, blossoms, and also yard stems. d-Optical bodies exist in necessary oils such as cypress, cardamom, celebrity anise, and also neroli. l-Optical body exists in vital oils such as blended lavender, Melaleuca, white lemon, and cinnamon leaves.
