What is Terpinol?

Terpinol has a yearn and also clove-like scent. Appearance is viscous liquid, yet has a tendency to formation, boiling point 218 ~ 219 ℃, 85 ℃/ 400Pa, melting point 35 ℃ (α-terpineol). It is primarily used in the deployment of perfumed soaps and also aesthetic essences such as lavender, lily of the valley, acacia, and also orange blossom. Pure α-terpineol can still be used to prepare lemon, orange, peach and other food flavors. Lots of ester substances prepared from Terpinol are likewise excellent flavors.

Terpinol, also referred to as sycamore oil and turpentine terpene alcohol, is normally present in vital oils such as pine oil, assorted lavender oil, karo timber oil, orange fallen leave oil, and also neroli oil. It is composed of α-pinene or β-pinene is a spice gotten by hydration to create terpene hydration diol, and then dehydration as well as fractionation. Terpineol is among the earliest artificial scents to be industrially created, and it is primarily made use of as a soap essence with a background of more than 100 years. Terpinol is a bulk seasoning product, the world’s yearly result is hundreds of tons. It is widely made use of in numerous fragrance solutions of everyday chemicals, particularly in scent solutions for soaps as well as synthetic cleaning agents, and also the dosage can reach 30%. IFRA has no restrictions.

The Role and Use of Terpinol

Terpinol is divided into two types: scent specification and also medicinal spec. Perfume-grade Terpinol has great scent adaptability and also stability to air and also in several scent mediums, as well as is widely made use of in flavor formulations for different purposes. It is likewise utilized as Include fresh breath representative; as body scent, it is frequently made use of basically such as lily, lilac, lily of the valley, acacia, sweet rhinoceros, orange bloom, etc. It is likewise a vital flavor in magnolia, gardenia, narcissus and also pine needle essences. Terpinol is cheap and commonly utilized in the blending of soap and aesthetic fragrances as well as top-quality tastes comparable to lilac fragrance, and also is utilized in pharmaceutical, electrical, ink as well as various other industries. The fraction consisting of 40% to 80% alcohol is called artificial ache oil, which is primarily utilized as a flotation protection foaming agent for non-ferrous metals.

Synthesis of Terpinol

The weight proportion of turpentine oil to 30% sulfuric acid is 1:1.7, as well as 10% Pergal is made use of as emulsifier. The response temperature is 28-30 ° C. After responding for 24 hours, allow it mean stratification, as well as the produced terpene diol hydrate crystals float on the acid water. After the acid water is discharged, the crystals as well as oil layer left in the response pot are cleaned 3 times with water, and after that cleaned with water down lye until neutral, Centrifugal purification, terpene diol hydrate formation. Throughout dehydration, the weight proportion of terpene diol hydrate as well as 0.2% sulfuric acid is 1:2. Stir as well as heat to steaming with direct heavy steam and also indirect steam. The response takes regarding 3 to 5 hours, and the reaction finishes when the specific gravity gets to d2040.933. Allow it represent stratification, as well as blurt the reduced layer of acid service. The turbid layer is reduced the effects of by including thin down lye, the lye is eliminated, and the oil layer is delegated clarify. The oil layer is fractionated and collected in sections according to the certain gravity of the fraction. The outcome of finished or semi-finished Terpinol is 55-60% of the input amount.

Preparation of Terpinol

A kind of new technology of Terpinol, comprises the following steps:

The first step, synthesizing terpene diol hydration: mixing 272g of industrial grade turpentine or α-pinene or β-pinene with acid water with a mass fraction of 20 to 75% into the reactor, The acid-water mixture is made of sulfuric acid, phosphoric acid, p-toluenesulfonic acid, chloroacetic acid, or two or more of them mixed with water to form a catalyst, and polyvinyl alcohol, organic One or more than one of the amine salts is used as an emulsifier, and the hydration reaction is carried out under the stirring condition of 100-1000rpm (preferably 400-800rpm) to generate crystalline terpene diol hydrate, and ultrasonic waves are used for the initial 2-4h of the reaction Aids in emulsification. The quality of water is 1~3 times of turpentine quality, preferably 1~2 times; The quality of catalyst is 20~75% of turpentine quality, preferably 25~50%; The quality of emulsifier is 0.001~0.2% of turpentine quality , 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, wood turpentine, and dry distillation turpentine. Its active ingredients are α-pinene and β-pinene. Industrial-grade α-pinene or β-pinene and α-pinene or β-pinene from other natural essential oils (such as eucalyptus oil, camphor oil, etc.) were used instead of turpentine as reaction raw materials.

In the second step, stop stirring after the hydration reaction is over, and use ultrasonic waves to vibrate and stir for a certain period of time, then settle and stratify, and release an acid-water mixture containing a small amount of terpene hydration diol from the bottom of the reactor, and the acid-water mixture after further clarification is prepared. When the appropriate ratio is reached, 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 a NaOH aqueous solution with a mass fraction of 3-5%. During the washing process, the acidic catalyst remaining between the crystals is fully recovered After the alkaline washing solution is recovered, 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 crystallized product that has been neutralized and washed by alkali is then washed with water under the action of ultrasonic intensification until the washing liquid is neutral to weakly alkaline. The washing liquid is released, and the washing liquid recovered each time is used for washing the next batch of reaction products, and the washing water that cannot be reused is put into the neutralization tank for clarification before recycling.

The fifth step, dehydration of terpene diol to synthesize Terpinol: the hydrated terpene diol crystallization product obtained through neutralization and water washing and the unseparated red oil contained in it are transferred to the dehydration reactor under the action of adding water and stirring, and are mixed with sulfuric acid, Phosphoric acid, p-toluenesulfonic acid, chloroacetic acid and other commonly used inorganic or organic acids or a mixture of two or more are used as catalysts, and within 1 hour after adding materials, ultrasonic waves are used to assist in accelerating the hydration of terpene diol in aqueous media. Dispersion and dissolution, dehydration reaction of terpene diol to produce Terpinol crude product commonly known as butter. In the dehydration reaction process, the quality of water is 1 to 2 times the quality of terpene diol hydrate and red oil, preferably 1 to 1.5 times; the quality of the catalyst is 0.1 to 2.5% of the quality of terpene diol hydrate and red oil, preferably 0.1 ~1.0%; the reaction temperature is 60~120°C, preferably 80~110°C; the reaction time is 2~12h, preferably 3~6h.

The sixth step is to separate and refine Terpinol: After the hydration reaction and dehydration reaction are completed, the lower acid layer is separated by standing. The crude terpineol product of the upper layer oil obtained, that is, butter, is neutralized with an aqueous sodium hydroxide solution with a mass fraction of 2 to 10% and washed with water until the washing liquid is neutral and slightly alkaline (pH=7 to 9), The crude product was obtained by standing and stratifying, and then the Terpinol product meeting the standard was obtained through vacuum distillation and continuous rectification.
