Product Description



Phosphorus pentachloride is a chemical used mainly to make medicines and colorful dyes. It's like a helper in chemistry to add chlorine to other substances to protect them. It also does a few other jobs, like helping with chemical reactions and making certain metal things stronger.

It is a white or pale yellow crystalline solid at room temperature and is known for its highly reactive and corrosive nature. It is primarily used in various chemical reactions, particularly in organic synthesis and as a chlorinating agent. One of its essential functions is as a chlorination reagent, where it replaces hydrogen atoms in organic molecules with chlorine atoms.

This substitution reaction is fundamental in the production of numerous organic compounds, including pharmaceuticals, pesticides, and plastics. It is also employed in the preparation of acyl chlorides, which are crucial intermediates in the synthesis of a wide range of organic chemicals.

Additionally, PCl5 finds application as a catalyst in condensation and cyclization reactions and can improve the grain structure of light metal castings. It is also used as an analytical reagent in laboratory settings. Phosphorus pentachloride is highly reactive and requires careful handling due to its tendency to release toxic chlorine gas when exposed to moisture. Its versatile reactivity and utility in various chemical processes make it a valuable tool in the field of chemistry, contributing to the production of numerous essential products.

IS 11744:1986 is like a set of rules for Phosphorus Pentachloride, Technical. These rules tell us what this chemical should be like and how to check if it's good enough. So, these rules make sure that when people use phosphorus pentachloride, it's safe and does its job properly.

4.     First, place the chemical into a specific plastic bag. Make sure the bag is at least 50 microns thick.

5.     Next, take this bag and put it either inside a steel drum or a special plastic container.

6.     Then, on each drum or container, you must include certain information.

7.     This information should mention what's inside, how much of it is in there, and any other details that the rules mention.

8.     If the chemical meets all the rules and standards, you can add a special mark to each drum or container. This special mark is called the "ISI mark."

9.     However, remember that to use this mark, the company making the chemical needs to get permission from the Bureau of Indian Standards.

10.  This permission is called a BIS license, and it's like a seal of approval to show that the product is good and safe.
