Embodiment 1

[0028] A safe storage-resistant odor composition, the preparation method of the odor composition comprises the following steps:

[0029] (1) According to the mass ratio, weigh 25g of 85wt% phosphoric acid and add it into the dispersion kettle, then add 50g of distilled water and 12.7g of pseudo-boehmite into the dispersion kettle, mix and stir evenly to obtain mixture A, and add 65g of hydroxyl Tetra-n-butylamine aqueous solution was added to the reactor, and 3.1g of light silica was added to the reactor, and after stirring evenly, the mixture A was added to the reactor, and then 4.5g of di-n-propylamine was added to the reactor and 9.7g of Rh-Mo-S ternary compound, seal the reaction vessel, conduct crystallization treatment at a temperature of 195°C for 24 hours, and filter the product to obtain a solid after the crystallization treatment is completed;

[0030] (2) Repeatedly wash the solid matter in the above step twice with deionized water until the washed product is neutra...

Abstract

The invention relates to the technical field of chemical odorizors and particularly relates to a high-safety and storage-resistant stink composition. The composition, namely high-stability odorizor capable of continuously releasing stink, is prepared by the steps of carrying out crystallization, high-temperature roasting and alkalization on phosphoric acid, pseudo-boehmite, hydroxy tetra-n-butylamine, light silicon dioxide, a di-n-propylamine, Rh-Mo-S ternary compound and the like so as to obtain a molecular sieve carrier, and carrying out absorption and curing on substances of ethanethiol, diethylamine, beta-cyclocitral, n-butyl mercaptan, thiophane and the like by virtue of the carrier. According to the composition, chemical hazards of stink materials can be reduced; and the compositioncan be applied to more industrial manufacturing fields.

Description

technical field [0001] The invention relates to the technical field of chemical odorants, in particular to a safe storage-resistant odor composition. Background technique [0002] Many substances emit odor. Odor is the most basic biological feeling, which stimulates the sense of smell and part of the sense of taste of the organism, thereby producing a sense of physiological disgust. Odor is a very unfriendly sensory experience, but this kind of odorous substances have some special and important applications in actual industrial production. For example, adding odorants to natural gas can act as a warning against leakage, and adding odorous substances to rubber or leather can prevent rats and other animals from biting and destroying. [0003] There are many types of odorous substances in nature, including organic odorous substances and inorganic odorous substances. For example, a large number of sulfides are odorous substances, including inorganic substances such as sulfur di...
