Embodiment 1

[0010] Embodiment 1: the s-butyl acetate with odor passes through the adsorbent bed in the deodorization device; under the action of the adsorbent, the odor of the sec-butyl acetate is directly adsorbed by the adsorbent; the adsorbent used has a specific surface area of ​​500 m 2 / g of activated carbon; the space velocity of sec-butyl acetate through the adsorbent bed is 8h -1 . The sulfur content at the inlet and outlet of the deodorization device was detected, and the chromatographic analysis results are shown in Table 1.

Embodiment 2

[0011] Embodiment 2: The adsorbent used is that the specific surface is 1000m 2 / g of activated carbon; the space velocity of sec-butyl acetate through the adsorbent bed is 10h -1 . Other steps are with embodiment 1. The sulfur content at the inlet and outlet of the deodorization device was detected, and the chromatographic analysis results are shown in Table 1.

Embodiment 3

[0012] Embodiment 3: The adsorbent used is a molecular sieve desulfurizer prepared according to the method of CN1288778; the space velocity of sec-butyl acetate through the adsorbent bed is 5h -1 . Other steps are with embodiment 1. The sulfur content at the inlet and outlet of the deodorization device was detected, and the chromatographic analysis results are shown in Table 1.

Abstract

The present invention discloses a method of removing the odor of the sec-butyl acetate; the sec-butyl acetate with the odor is put on the adsorbent bed layer of the deodorant device; with the influence of the adsorbent, the odor of the sec-butyl acetate can be directly absorbed by the adsorbent; the space velocity for the sec-butyl acetate to pass through the adsorbent bed layer is 0-20 h -1. The present invention has the simple technology; the deodorant effects of the sec-butyl acetate is good. Besides, the cost is low and the invention has no pollution.

Description

technical field [0001] The present invention relates to a kind of method of deodorization, relate to a kind of method of deodorizing in sec-butyl acetate specifically. Background technique [0002] Second-butyl acetate, also known as second-butyl acetate and second-butyl acetate, is one of the four isomers of butyl acetate. It is a colorless, flammable, fruity-flavored liquid. It has the same properties as other isomers. Similar in most cases, can dissolve a variety of resins and organics. Its boiling point is lower than that of commonly used n-butyl ester and isobutyl ester, and its evaporation rate is faster. Mainly used as solvent, pharmaceutical industry, reaction medium, extractant component, metal cleaning agent, fruit flavor, etc. [0003] From acetic acid and refinery C 4 The sec-butyl acetate product obtained by the reaction will emit a foul smell, which not only pollutes the environment, but also stimulates human olfactory cells and endangers human health. The ...
