Usage

General Description

Cyclopentyl acetate is a colorless liquid that is commonly used as a synthetic flavoring agent in the food and beverage industry. It has a fruity, apple-like odor and is often used in the production of fragrances and perfumes. Cyclopentyl acetate is also used as a solvent in the manufacturing of various products, including lacquers, varnishes, and paints. It is considered safe for use in food products and is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration. However, it should be handled with care due to its flammability and potential for irritation to the skin and eyes.

METHOD FOR PRODUCING DICARBOXYLIC ACID

A method for producing dicarboxylic acid. The method includes: subjecting a raw material system including a cyclic olefin and a lower monocarboxylic acid to an addition reaction in the presence of an addition reaction catalyst to generate an intermediate product system including cyclic carboxylic acid ester; and subjecting the intermediate product system including cyclic carboxylic acid ester to a ring-opening and oxidation reaction in the presence of an oxidant and an oxidation catalyst to generate a corresponding dicarboxylic acid product. The addition reaction in the dicarboxylic acid synthesis route achieves a high single-pass conversion rate, and the selectivity of the corresponding cyclic carboxylic acid ester is high. The addition-oxidation synthesis route achieves faster reaction rates for both the addition reaction and oxidation reaction, and high yield of corresponding dicarboxylic acid product. The addition-oxidation based synthesis route is suitable for continuous, stable and large-scale production of corresponding dicarboxylic acid product.

Application of Yttrium Iron Garnet as a Powerful and Recyclable Nanocatalyst for One-Pot Synthesis of Pyrano[2,3-c]pyrazole Derivatives under Solvent-Free Conditions

The application of yttrium iron garnet (YIG) superparamagnetic nanoparticles as a new recyclable and highly efficient heterogeneous magnetic catalyst for one-pot synthesis of pyrano[2,3-c]pyrazole derivatives under solvent-free conditions, as well as etherification and esterification reactions are described. The advantages of the proposed method include the lack of organic solvents, clean reaction, rapid removal of the catalyst, short reaction times, excellent yields, and recyclability of the catalyst.

Method for preparing cyclopentanol from cyclopentene

The invention relates to a method for preparing cyclopentanol from cyclopentene. Cyclopentene and acetic acid are mixed for an esterification reaction, cyclopentyl acetate is generated, a catalyst adopts cerium nitrate modified sulfonyl cation exchange resin during a transesterification reaction, and the exchange capacity of cerium ions is 10%-30% of that of resin mass; the conversion rate of the esterification reaction is remarkably increased; during the transesterification reaction of crude cyclopentyl acetate and methanol, the transesterification reaction is catalyzed through granular CaO and a sodium methylate composite catalyst dissolved in a reaction liquid, cyclopentyl acetate and methanol can be catalyzed for the transesterification reaction, a small amount of water brought into reaction raw materials can be removed, difficulty caused by CaO hydrolysis and product separation is avoided, and the pollution problem of an existing process is effectively solved.
