Sinochem News On April 19, a seminar on the development and application of high-end fluorine materials hosted by the China Fluorosilicone Organic Materials Industry Association was held in Zigong.

Precautions when using CAS#151-21-3 sodium dodecyl sulfate reagent

Sodium lauryl sulfate is also called sodium lauryl sulfate/sodium lauryl sulfate/SDS. It is generally white or milky white needles or powder. It has a slightly fatty smell, has a smooth feel, and can decompose in moist air. The molecular formula is CH3(CH2)11OSO3Na, molecular weight 288.38, CAS number 151-21-3, slightly soluble in ethanol, almost insoluble in chloroform, ether and light petroleum. Melting point: 204~207℃. Store in a sealed, cool and dry place.

Interpretation of the "Guidelines for Safety Risk Investigation and Management of Chemical Industry Parks"

Reporters learned from the Ministry of Emergency Management on the 21st that in order to effectively prevent and control major safety risks in chemical industry parks, the Ministry of Emergency Management has recently revised and issued the "Guidelines for the Investigation and Management of Safety Risks in Chemical Industry Parks" to further guide, standardize and strengthen the investigation and management of safety risks in chemical industry parks.

How to determine the expiration date of chemical reagents?

The expiry date of reagents is an important factor affecting the accuracy of experimental results. In actual use, people are always accustomed to using the production date to judge the effectiveness of chemical reagents. In fact, this is wrong.

Analysis of high-purity reagents and classification of high-purity reagents

A reagent with a purity far higher than that of premium grade is called a high-purity reagent. It is developed on the basis of universal reagents and is a pure reagent produced by special methods for specialized purposes. High purity reagents control the impurity content, while reference reagents control the main content. Reference reagents can be prepared using standard solutions, but high-purity reagents cannot be used for the preparation of standard solutions (except for elemental oxides).

Comprehensive understanding of chemical reagents from multiple perspectives

According to experts in the chemical industry of chemical reagent companies, chemical reagents are relative standard substances for conducting chemical research and component analysis, and are an important condition for technological progress. They are mainly suitable for the synthesis, separation, qualitative and quantitative analysis of substances. In other words, they are the eyes of chemical reagent workers. In the daily work of factories, schools, hospitals, and research institutes, chemical reagents are indispensable.

Classification of sodium carbonate (soda ash)

Soda ash is mainly divided into light soda ash (referred to as light soda ash) and heavy soda ash (referred to as heavy soda ash) according to different densities.

Application scope of industrial salt
