Sodium hypochlorite pentahydrate Chemical Properties,Usage,Production

Description

Sodium hypochlorite pentahydrate crystals are an excellent alternative to traditional sodium hypochlorite solutions.

Chemical Properties

Pale yellow crystals.

Uses

Individual sodium hypochlorite pentahydrate crystals (without nitro radicals) exhibit a strong oxidizing power, converting secondary alcohols to the corresponding ketones for industrial and laboratory use.

Definition

ChEBI:Sodium hypochlorite pentahydrate is a hydrate consisting of sodium hypochlorite and 5 molar equivalents of water.

Synthesis

The high concentration Sodium hypochlorite solution was prepared by passing chlorine gas into 45~48% Sodium hydroxide solution, filtering to remove the precipitated Sodium chloride, and cooling the filtrate to about 15℃, Sodium hypochlorite pentahydrate crystals were precipitated, and the product was obtained by centrifugal filtration.

Solubility in organics

Insoluble
