Properties and stability

The current main industrial product is low viscosity (1.5~2.5Pa·s, 25℃) methylhydantoin epoxy resin. Hydantoin epoxy resin has low viscosity and good process performance. Its viscosity is much lower than bisphenol A epoxy resin. It has good process performance without adding diluent. It has good thermal stability, high heat resistance, and its insulation The potting material can be used for more than 5000 hours at 180°C and has a service life of 40 years at 130°C. It has good weather resistance. The coating is not easy to yellow and powder when exposed to sunlight or ultraviolet rays, and its performance is better than that of bisphenol A-type rings. Oxygen resin and acrylic resin coatings are also outstanding in their salt spray resistance and corrosion resistance; they have outstanding electrical properties under high voltage and ultra-high voltage, especially excellent arc resistance and leakage trace resistance; they have strong polarity and viscosity Low, so it has good wetting ability and adhesion to glass fiber, carbon fiber and various fillers. A large amount of fillers can be added without reducing the processability, thereby reducing the linear expansion coefficient and cost.

Storage method

Store dry and sealed.

Synthesis method

It is obtained by reacting acetone cyanohydrin and ammonium carbonate aqueous solution at 50-80°C.

Purpose

It is used in the synthesis of amino acids, and can also be used as special epoxy resin and water-soluble resin, bactericide, preservative, etc. Its derivatives such as 1,3-dichloro-5,5-dimethylhydantoin can be used as chlorinating agent and disinfectant, 3-hydroxymethyl-5,5-dimethylhydantoin Can be used as formaldehyde agent, preservative, etc.

Storage method

This product should be sealed in Store in a cool and dry place.

Synthesis method

By8-Hydroxyquinoline is obtained by iodination.

Purpose

Used as anti-amidamide Pakistani medicine, antiseptics, metal chelating agents, cation analysis reagents. Diiodoquinoline, quiniodoform, and clioiodoquinoline are all halogenated8-Hydroxyquinoline intestinal anti-amoebic drugs are effective against amoebic dysentery and have no effect on extraintestinal amebic protozoa. In recent years, it has been reported abroad that this type of drug can cause subacute myelooptic neuropathy, so it has been banned in Japan and the United States. However, this disease is less common with iodoquinoline than with clioquinoline.
