[0027] see figure 1 , the preparation method of the compound with caramelized butter flavor of one embodiment is a preparation method of the compound with caramelized butter flavor of the above-mentioned embodiment, comprising the following steps:
[0028] Step S110: react phenylacetic acid with thionyl chloride to obtain phenylacetyl chloride.
[0029] Wherein, the structural formula of phenylacetyl chloride is as follows:
[0030] Specifically, the molar ratio of phenylacetic acid to thionyl chloride is 1:1.05˜1:1.5. In one embodiment, in the step of reacting phenylacetic acid with thionyl chloride, phenylacetic acid is firstly added to the reaction vessel, and then the thionyl chloride is slowly added. Since the reaction between phenylacetic acid and thionyl chloride is relatively fast, thionyl chloride is slowly added dropwise in the reaction process to avoid the reaction being too fast and at the same time producing a large amount of tail gas which is difficult to com...
Embodiment 1
[0055] The preparation process of the compound with burnt cream taste of the present embodiment is as follows:
[0056] (1) preparation of phenylacetyl chloride:
[0057]
[0058] In 10L reactor, add phenylacetic acid (2.5L), slowly add thionyl chloride (1.5L), be warming up to 78 ℃ of reaction after dripping finishes, the tail gas that produces in the reaction process is 10% sodium hydroxide with mass concentration The aqueous solution was absorbed, stirred for 1 hour, and then distilled under reduced pressure to obtain phenylacetyl chloride (3.0 kg).
[0059] (2) preparation of furfuryl thiophenylacetate:
[0060]
[0061] In 10L reactor, add furfuryl mercaptan (2.0L, commercially available Hubei Hongxin Ruiyu Fine Chemical Co., Ltd.), under 25 ℃ of conditions, slowly add phenylacetyl chloride (3.0kg) dropwise, and react 3 hours, the tail gas produced in the reaction process was absorbed with an aqueous sodium hydroxide solution with a mass concentration of 10%. Aft...
Embodiment 2
[0070] The preparation process of the compound with burnt cream taste of the present embodiment is as follows:
[0071] (1) preparation of phenylacetyl chloride:
[0072] In 10L reactor, add phenylacetic acid (2.5L), slowly add thionyl chloride (1.5L), be warming up to 70 DEG C of reaction after dripping finishes, the tail gas that produces in the reaction process is 10% sodium hydroxide with mass concentration The aqueous solution was absorbed, stirred for 2 hours, and then distilled under reduced pressure to obtain phenylacetyl chloride (3.0 kg).
[0073] (2) preparation of furfuryl thiophenylacetate:
[0074] In the 10L reaction kettle, add furfuryl mercaptan (2.0L, commercially available from Hubei Hongxin Ruiyu Fine Chemical Co., Ltd.), under 30 ° C, slowly add phenylacetyl chloride (3.0kg) dropwise, and react 2 hours, the tail gas produced in the reaction process was absorbed with an aqueous sodium hydroxide solution with a mass concentration of 10%. After the complet...
