Abstract
The invention discloses a method for removing mercaptan odour in mercaptan organotin. The method comprises the following specific steps that: under the states of normal temperature and normal atmosphere, an odour preventing agent consisting of odour preventing grass, spices, an ultraviolet absorbent, a free radical absorbent is added into a mercaptan organotin finished product; the addition amount of the odour preventing agent is 0.01 to 1 percent of the weight of the mercaptan organotin finished product; and a mixture is stirred and evenly mixed. As the odour preventing agent is used, the method can eliminate foreign odour produced by the mercaptan organotin in the processing process and produce light faint scent; and the odour preventing agent has stable performance, does not have any chemical property reaction with the mercaptan organotin and has good deodorization effect on various organisms. In addition, the method has simple process and convenient production.
Description
Technical field
The present invention relates to the fine chemistry industry production field, particularly relate to a kind of method of removing thiol smell in the thiol organotin.
Background technology
Because thiol organotin has the mercaptan taste, in the PVC course of processing, produce offending smell, cause PVC manufacturer that the thermo-stabilizer of this high-efficiency environment friendly of thiol organotin is produced resentment, make the popularization of thiol organotin be subjected to some restrictions.
The fine chemical material of 2003 2 phases and intermediate have been introduced a kind of chemical mask agent, this product is formulated by mask agent, a small amount of natural perfume and dispersant with high efficiency, can effectively remove the various peculiar smell in the Chemicals such as ester class, benzene, ketone, alcohol, aldehyde, alkane, ammonia, and distribute delicate fragrance for a long time.
Shenzhen's gold is risen imperial trade Co., Ltd, and a kind of trade mark is provided is the screening flavor deodorant addtives of MOCOO-851, and its major ingredient " hides the flavor grass " and belongs to ocean silanol class biology.
Up to the present, for the method that solves thiol organotin mercaptan taste, any document, patent report have not been seen as yet.
Summary of the invention
Technical problem to be solved by this invention is: for solving thiol organotin produces offending smell in the PVC course of processing problem, provide a kind of method of removing thiol smell in the thiol organotin.
The technical scheme that the present invention solves its technical problem employing is: under the normal temperature and pressure state, in the thiol organotin finished product, add a kind of mask agent of mainly forming by screening flavor grass, spices, UV light absorber, free radical sorbent material, the addition of mask agent is 0.01～1% of a thiol organotin finished weight, and restir also mixes.
The present invention has following major advantage:
One. in the thiol organotin finished product, add a kind of mask agent of mainly forming, can eliminate the peculiar smell that thiol organotin produces in the course of processing, produce light delicate fragrance by screening flavor grass, spices, UV light absorber, free radical sorbent material.
Above-mentioned mask agent, it hides flavor principle and is: the one, improve the boiling point of volatile component in the medium, and form one deck at liquid level and cover net and reduce its volatility, thereby cover the stimulation peculiar smell.The 2nd, infiltrate the surface of material, adsorb and these materials that neutralize in monomeric peculiar smell react and decompose rapidly, reach the purpose of eliminating peculiar smell.
They are two years old. the mask agent stable performance: the reaction of any chemical property does not take place with thiol organotin, and obvious to each type organic deodorizing effect.
They are three years old. and technology is simple, is convenient to produce.
Embodiment
