Title: The Production and Applications of T-4 Bis[2-(Hydroxy-κO)benzoato-κO]lead in the Chemical Industry

Introduction

T-4 bis[2-(hydroxy-κO)benzoato-κO]lead, commonly referred to as T-4, is a lead-based heteropolyacid that has been widely used in various chemical reactions due to its strong acidity and ability to activate a variety of substrates.
T-4 has garnered attention in recent years due to its unique properties and versatile applications in various industries, particularly in the chemical industry.
This article aims to explore the production and applications of T-4 in the chemical industry.

Production of T-4

T-4 can be produced through a multi-step synthesis process that involves the reaction of lead nitrate with sodium hydroxide, followed by treatment with sodium benzoate and hydrolysis.
The synthesis process can be represented as follows:

Pb(NO3)2 + 2 NaOH → Pb2(OH)2NO3 + 2 NaNO3
Pb2(OH)2NO3 + C6H5CO2H → Pb2(C6H5CO2H)2 + 2 HNO3

The first step involves the reaction of lead nitrate with sodium hydroxide to form lead hydroxide and nitric acid.
The lead hydroxide is then treated with sodium benzoate, which undergoes hydrolysis to form benzoic acid, resulting in the formation of T-4.
