Addition Reaction of (+) -Limonene, 2-Pinene, and 2 (10) -Pinene with C1 C4 Alcohols in the Presence of Synthetic Zeolites

Abstract

Reactions of monoterpene hydrocarbons with alcohols (C1•`C4) were carried out in the presence of synthetic zeolites. The addition of (+)-limonene, 2-pinene, and 2 (10)-pinene to alcohols gave the corresponding terpenyl ethers as the major products. Some reaction products could be used as perfume bases.

Limonene ethers from tire pyrolysis oil

“…In this work, the heterogeneous catalysts were tested to be used for limonene alkoxylation. It is known that several zeolites with strong Bronsted acid sites are effective for this reaction [12][13][14].…”

Limonene ethers from tire pyrolysis oil

“…bZeolite is a large pore 12-ring zeolite with a three-dimensional system of channels, which selectively catalyzes the addition of methanol to the double bond of limonene [7][8][9][10]. This paper describes limonene enrichment from tire pyrolysis oil distillation and continuous limonene etherification by reacting limonene-enriched distillation fractions with methanol using a continuous microreactor.…”
