Embodiment 1

[0035] Take 100g of orange peel, add 200mL of calcium hydroxide aqueous solution with a concentration of 5% and soak for 24 hours, then add 150mL of copper sulfate aqueous solution with a concentration of 1.5%, soak for 24 hours, crush and sieve to obtain particles with a particle size of less than 7mm, after squeezing, collect The juice is filtered with a 420-mesh filter, and the filtrate is collected to obtain the orange peel extract, with an extraction rate of 72.5%.

[0036] The GC-MS detection result shows that the content of caprylic acid in the orange peel extract is 1.35%, the content of hexadecanoic acid is 0.97%, the content of limonene is 48.60%, the content of myrcene is 13.58%, and the content of linalool oxide I The content is 11.58%, the content of linalool oxide II is 6.22%, and the content of germienne D is 8.12%.

Embodiment 2

[0038]Take 100g of pomelo peel, add 150mL of calcium hydroxide aqueous solution with a concentration of 10% (mass volume ratio is 1:1.5~2) and soak for 12h, then add 180mL of copper sulfate aqueous solution with a concentration of 1.2%, soak for 14h, crush and sieve Particles with a particle size of less than or equal to 7mm are obtained. After squeezing, the juice is collected, filtered with a 360-mesh filter, and the filtrate is collected to obtain grapefruit peel extract, with an extraction rate of 74.3%.

[0039] GC-MS detection result shows, the content of octanoic acid in grapefruit peel extract is 1.69%, the content of hexadecanoic acid is 1.35%, the content of limonene is 48.25%, the content of myrcene is 11.97%, the content of linalool oxide I The content is 13.01%, the content of linalool oxide II is 6.15%, and the content of germine D is 8.21%.

Embodiment 3

[0041] Take 100g of orange peel, add 180mL of calcium hydroxide aqueous solution with a concentration of 7% and soak for 16h, then add 200mL of copper sulfate aqueous solution with a concentration of 1%, soak for 18h, crush and sieve to obtain particles with a particle size of less than or equal to 7mm, after pressing, Collect the juice, filter it with a 300-mesh filter, and collect the filtrate to obtain the orange peel extract, with an extraction rate of 73.8%.

[0042] The GC-MS detection result shows that the content of caprylic acid in the orange peel extract is 1.47%, the content of hexadecanoic acid is 1.24%, the content of limonene is 49.56%, the content of myrcene is 14.22%, and the content of linalool oxide I The content is 15.49%, the content of linalool oxide II is 9.10%, and the content of gerbilene D is 8.71%.

Abstract

The invention relates to the field of fine chemical engineering, in particular to a citrus fruit skin extract and an extracting method thereof. The obtained citrus fruit skin extract comprises 1.35-2.13% of caprylic acid, 0.97-1.48% of hexadecanoic acid, 48.25-51.20% of limonene, 11.97-14.94% of myrcene, 11.49-16.15 % of linalool oxide I, 6.15-11.14% of linalool oxide II and 8.12-8.74% of germacrene D. By using the extract, the removal rate of the ammonia is 100% and the removal rate of formaldehyde is 85.09-89.55%; and coating additives for removing the ammonia and the formaldehyde can be prepared.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a citrus plant peel extract and an extraction method thereof. Background technique [0002] In recent years, with the development of my country's economy and the improvement of people's living standards, people's awareness of environmental protection and health requirements are increasing day by day, and the pollution caused by toxic and harmful substances in building decoration materials to the environment and the impact on human health have become increasingly prominent. Toxic and harmful substances mainly come from pollutants such as formaldehyde and ammonia released from building decoration materials. Among them, formaldehyde mainly comes from plywood, joinery board, paint, coating and other decorative materials used for interior decoration. It is a colorless and soluble irritating gas, which is relatively harmful to the human body. It can cause eye, skin, etc. It can stimulate...
