The invention relates to a method for synthesizing o-ethoxybenzoic acid from salicylic acid, which comprises the following steps: adding salicylic acid, acetone and potassium hydroxide into a reaction bulb, dropwisely adding bromoethane while stirring at room temperature, heating under reflux for 9-15 hours, recovering the acetone under reduced pressure, adding water and liquid alkali, heating under reflux for 2-4 hours, cooling to room temperature, regulating the pH value to 3-4 with glacial acetic acid, cooling to 1-15 DEG C, separating by vacuum filtration, washing with water, and carrying out vacuum drying to obtain the o-ethoxybenzoic acid, wherein the salicylic acid:potassium hydroxide:bromoethane:liquid alkali mol ratio is 1:(2.0-2.5):(2.1-2.5):1.5. The method has the advantages of simple technique, low raw material cost, high yield and good quality, and is convenient to operate and convenient for industrial production.

The invention discloses a Chinese medicine composition anti-wrinkle multi-function liquid, its preparation and application. The anti-wrinkle multi-function liquid comprises the following ingredients: 11-13 weight portions of the root of kudzu vine, 12-14 weight portions of rehmannia glutinosa, 7-9 weight portions of gingko, 11-13 weight portions of dark plum, 12-14 weight portions of leonurus, 4-6 weight portions of radix salvia miltiorrhizae, 6-8 weight portions of liquorice, 7-9 weight portions of Ligusticum wallichii, 6-8 weight portions of Angelica sinensis, 5-7 weight portions of Semen Cuscutae, 3-5 weight portions of glossy ganoderma, 4-6 weight portions of rhizoma cyperi, and 8-10 weight portions of ginseng. The multi-function liquid is light yellow and tasteless. The trade name ofthe multi-function liquid is aromlotus Chinese medicine composition anti-wrinkle multi-function liquid. The direct use of the multi-function liquid on the skin can effectively remove wrinkles, and can be absorbed by the skin effectively, so that the effects of skin care and skin beauty are achieved. According to the invention, no chemical additives are added in the multi-function liquid, and the multi-function liquid uses all natural extracts, so that the effects are realized depending on the Chinese medicine extracts completely; and the natural extracts are obtained by mixed extraction according to Chinese medicine formula, so that the characteristics of the compatibility of Chinese medicines are really shown.

Disclosed is a novel supercritical phase salicylic acid synthesis process, which comprises making sodium phenolate through neutralizing phenol with NaOH aqueous solution, drying and grinding to obtain solid sodium phenolate, subjecting the sodium phenolate and carbon dioxide to supercritical homogeneous phase carboxylation reaction (Kolbe-Schmitt reaction) in heavy pressure reaction kettle, obtaining sodium salicylate, acidifying to prepare the salicylic acid.
