Description
Technical Field
The utility model relates to an ice flakes production facility field especially relates to an extract fenchyl alcohol's device in the accessory substance of following production borneol.
Background
Fenchyl alcohol, also known as cumyl alcohol, known under the chemical name 1, 3, 3-trimethyl-2-norbornanol, has a camphor-like odor with a citrus note, has a bitter lime-like flavor, is slightly soluble in water, is soluble in ethanol, and is found in natural mixtures in spruce oil and pine oil. The main application is as follows: in GB 2760-1996, food flavors are defined which are approved for use. Fenchyl alcohol is widely used in costustoot, grass, citrus or certain floral essences and cosmetics, can also be used in daily chemicals such as antiperspirants, fabric softeners and liquid detergents, and can also be esterified with various organic acids to obtain fenchyl alcohol ester perfume. Currently fenchyl alcohol is obtained mainly by two routes, one is by organic synthesis, for example, starting with fenchyl ketone, by grignard reaction with ethylmagnesium bromide or by reduction with sodium alkoxide. The second method is separation and extraction from natural essential oil containing fenchyl alcohol.
The synthesis of borneol has many technical routes, and the most mature and industrialized production is that alpha-pinene is extracted from turpentine, and the alpha-pinene and anhydrous oxalic acid are subjected to esterification reaction under the catalysis of an acid catalyst to generate borneol oxalate, and then the borneol oxalate is subjected to saponification reaction with sodium hydroxide to obtain crude borneol, and the crude borneol is further purified to obtain the target product of borneol.
In the esterification reaction process of borneol production, due to the isomerization of alpha-pinene, besides the target product of borneol oxalate, a large amount of isomerization products such as camphene, dipentene, camphor, fenchyl alcohol ester, terpineol ester, other linalool ester and the like are generated. In the current production mode, only the by-products in the borneol production are simply divided into light components (light oil) and heavy components, the heavy components are mixed into borneol oxalate for saponification, and then alcohol mixtures such as fenchyl alcohol, terpineol, other linalools and the like are generated in addition to the target product borneol, wherein the fenchyl alcohol is mainly used, the content is about 40-60%, and 17-20% of borneol (borneol and isoborneol) is dissolved.
When the alcohol mixture is traditionally fractionated, because the temperature at the top of the tower is not easy to control, the borneol is easy to block the pipeline of the rectifying tower, and the production is stopped.
