Embodiment 1

[0032] Weigh 3g of lignin, 5g of montmorillonite and 7ml of deionized water, put them in a reaction kettle, add 0.1mol / L H3PO43ml, stir and react at 200°C, separate and wash with water after fully reacting to obtain biochar / clay composite material. The biochar and montmorillonite composite material were calcined for 3 hours at 400° C. under the protection of nitrogen atmosphere to obtain the lignin biochar and montmorillonite composite material.

[0033] Before use, weigh 30 g of biochar and montmorillonite composite material and desorb at 0.01 MPa for 3 hours. Then the biochar and the montmorillonite composite material were transferred into an oven with 50g of fresh gardenias. Adsorb at room temperature for 10 hours after airtight. Afterwards, the above-mentioned adsorbed biochar and montmorillonite composite material were eluted with absolute ethanol and n-hexane, and the obtained eluate was evaporated with a rotary evaporator until no liquid drops fell down, and gardenia h...

Abstract

The invention provides a preparation method and application of an efficient adsorbing material for cape jasmine flower essential oil top note extraction. The preparation method comprises the followingsteps: taking lignin, montmorillonite and deionized water, putting the materials into a reaction kettle, adding 0.1 mol / L dilute acid, stirring for a reaction at 80-250 DEG C, fully reacting, separating, washing with water to obtain the biochar and clay composite material, and roasting the biochar and montmorillonite composite material at 250-700 DEG C under the protection of nitrogen for 1-10 hours to obtain the lignin biochar and montmorillonite composite material.

Description

technical field [0001] The invention relates to the technical field of gardenia essential oil extraction, in particular to a preparation method and an application of a high-efficiency adsorption material for extracting gardenia essential oil head fragrance. Background technique [0002] Gardenia (scientific name: Gardenia jasminoides), also known as gardenia and yellow gardenia, belongs to Rubiaceae Gentianae. It belongs to Rubiaceae and is an evergreen shrub with luxuriant branches and leaves, evergreen leaves and fragrant flowers. It can be planted in most parts of China. The flowering period is generally from May to July. It is also known as sparrow flower, wild osmanthus, yellow gardenia, etc. It is one of the eight major fragrant flowers in China. It is cold in nature and sweet and bitter in taste. . Flowers vary in size and color. Compared with large flowers, small flowers have a stronger fragrance, while white flowers have a better fragrance, with a sweet fruity and...
