Methods and systems for recovering terpenes and controlling the composition of terpenes collected from wood drying processes are provided. In particular, a sorbent having adsorbed materials, including terpenes, from a wood drying process can be desorbed in a desorber, resulting in a gaseous stream containing terpenes, which can be condensed and collected from the gaseous stream. The conditions of desorption can be controlled to ensure a desirable amount of alpha-pinene and beta-pinene relative to other terpenes, such as dipentene and camphene, in the collected terpenes.

The application relates to the field of organic synthesis and discloses a method for continuously producing camphene aldehyde from pinene by one-step method and application of the method, which comprises the following steps: continuously feeding an organic solution of alpha-pinene and neutral organic peroxide into a reactor in the presence of a main catalyst A and an auxiliary catalyst B to perform continuous contact reaction, wherein the main catalyst A is an oxidation catalyst, and the auxiliary catalyst B contains alkali metal and / or alkaline earth metal. According to the method, camphene aldehyde can be directly produced from pinene by one-step method of epoxidation and isomerization rearrangement reaction, and the selectivity and yield of the camphene aldehyde product are relatively high. The method avoids complicated operation steps such as rectification purification required by a two-segment reaction process, reduces the reaction process, and simultaneously adopts a continuous production process, so that production is efficient, convenient and stable.

This invention discloses a poly(4-methyl-1-pentene) aerogel, its preparation method, and its applications. By using camphene as a solvent for poly(4-methyl-1-pentene), a thermally induced phase separation process is initiated by controlling the cooling rate, followed by conventional drying to obtain a white aerogel with good self-supporting properties. The preparation method is simple and mild, requiring no complex processes or expensive equipment, and can be produced on a large scale. The aerogel possesses a rich microporous structure and extremely high solar reflectivity, making it suitable for radiative cooling for passive cooling. Furthermore, the aerogel prepared by this method exhibits excellent superhydrophobicity and thermal insulation properties, enhancing its potential for outdoor applications.

This invention relates to a continuous production process for the preparation of sandalwood 803. The preparation method of the phosphate catalyst includes the following steps: dissolving Zr(NO3)4·5H2O and Ce(NO3)3·6H2O in water to prepare a Zr-Ce nitrate mixture; dissolving phosphoric acid and / or its acidic salt in water to obtain a phosphoric acid and / or its acidic salt solution; adding the phosphoric acid and / or its acidic salt solution to the Zr-Ce nitrate mixture, adjusting the pH, stirring, allowing it to settle, filtering, washing, drying, and calcining to obtain the phosphate catalyst, thus completing the reaction. Compared with the prior art, this invention provides a phosphate catalyst with high safety, high activity, high stability, and strong acidity, achieving a high-yield conversion of phenol camphene, increasing the content of meta-terpene phenols, and thus increasing the content of terpene cyclohexanol in sandalwood 803. It can also be used stably and for a long time in a fixed-bed gas-phase reaction process.
