Definitions
- the present invention relates to an element method of producing hydrogen by reacting phos- phasic primary amine with hydrogen chloride, which is used in the synthesis of isocyanates, as a raw material, and converting hydrogen chloride into hydrogen by catalytic phase reaction.
- sulfur contained in hydrogen chloride must be eliminated.
- Sulfur content in the element which is a by-product in the synthesis of isocyanates, comes from hydrogen monoxide, carbon oxide, sulfuric acid gas in hydrogen monoxide used in phosgene formation, and in the same element in gen. Examples include sulfuric acid gas mist and sulfur in mines used for isocyanation. Most of these sulfur components are considered to be mixed with the isocyanates and discharged together with the isocyanates during the synthesis of the isocyanates. Affects the properties of hydrogen chloride during oxidization.
- the present invention was made in order to solve the above-mentioned problem, and the purpose of this is to prevent the practical use of the amount of hydrogen chloride that is supplied to the production of chlorine without the use of hydrogen chloride. It is to provide a method that can be reduced to a level that does not exist.

- the body containing chlorine as a main component is separated from the main component containing oxygen. It is carried out within a range in which an element that is determined by temperature can exist in the state. The lower the temperature, the lower the compressive force because the compressive force becomes lower, but in general, there are problems such as equipment. Therefore, the compression cooling is decided in consideration of the suitable economic conditions in this area.In normal operation, it is carried out at 0. 55 Pa of chlorination and cooling degree of about 40.
- the unhydrogenated hydrogen chloride as a part of the material for washing with water and hydrogen chloride. That is, in the example shown in 2, part or all of the body containing the element as the main component or the body containing the separating element as the main component is reacted and fed. By doing so, there is a point that the oxygen level can be reduced.
- the washing of this element is not particularly limited, and the washing can be performed as in the conventional case.
- the content of the content may be mixed into the isocyanate compound process and may be recycled to the hydrogen chloride conversion process again. It refers to the value measured in water in this element, for example, by water analysis by the trapped ion chromatography method. It is preferable that all and / or all of the materials obtained in this way and used for the synthesis of the above-mentioned isocyanates are used. This has the potential to prolong the life of the hydrogen chloride process.
- the Ming-Ion method can significantly reduce the amount of hydrogen chloride, which is a by-product in the synthesis of isocyanates, without the need for hydrogen chloride diffusion, which allows the formation of hydrogen by hydrogen chloride formation. Can be performed stably over a long period of time
