118-52-5 - Introduction

Dichloro dimethyl Maine (Dichlorodimethylhydantoin, DCDMH) is a kind of organic compounds.
Nature:
Appearance: white crystalline powder
Density: 1.59g /cm3
Soluble: slightly soluble in water, easily soluble in organic solvents such as alcohol, ether, etc.

Purpose:

Disinfectant: DCDMH has a strong antibacterial and bactericidal effect, widely used in swimming pools, industrial circulating water, sewage treatment, family health and medical health and other fields.
Bleach: DCDMH can be used as a bleach, especially in the pulp and paper manufacturing process.
Preparation:
DCDMH can be obtained by the reaction of dimethylurea with chlorine gas. The specific preparation method can be slightly complicated and needs to be carried out under appropriate laboratory conditions.

Safety information:
DCDMH can decompose and produce toxic chlorine gas under the conditions of high temperature, high humidity and easy burning, so pay attention to ventilation and avoid heat sources when storing and using.
In case of ingestion, contact with eyes or skin, rinse immediately with plenty of water and seek medical treatment.
DCDMH is toxic to aquatic organisms and should be avoided from entering natural water bodies.
