What You'll Learn
Leo Baekeland's early life and career
Leo Hendrik Baekeland was born on November 14, 1863, in Ghent, Belgium. His father, Charles Baekeland, was a cobbler, and his mother, Rosalia Merchie, was a housemaid. Baekeland had a strong interest in science and chemistry, which led him to pursue higher education in these fields. He attended the Koninklijk Atheneum in Ghent and later studied at the University of Ghent, where he earned a doctorate in chemistry in 1882 or 1884 at the age of 21. After completing his education, Baekeland worked as a lecturer and then became an associate professor of chemistry at the University of Ghent.
In 1889, Baekeland immigrated to the United States with his wife, Celine Swarts, the daughter of his professor. They had two children. In the US, he began working as a research chemist for a photography company, the E. and H.T. Anthony Company. During this time, he also invented a process to develop photographic plates using water instead of other chemicals, which he patented in Belgium in 1887.
Baekeland soon left the Anthony company and, in 1891, set up his own business as a consulting chemist. He then turned his attention to producing a photographic paper that could be developed under artificial light. After two years of intensive effort, he perfected the process and named the paper
With the money he made from the sale of his company, Baekeland purchased a house in Yonkers, New York, where he set up his own laboratory. He then began working on a synthetic substitute for shellac, which was made from the shells of Asian lac beetles at the time. In 1907, he successfully created Bakelite, a groundbreaking material made from phenol and formaldehyde. It was the first thermosetting plastic, meaning it retained its shape after being heated. Bakelite revolutionised multiple industries, including electrical insulation and consumer goods, and marked the beginning of the modern plastics industry.

The invention of Bakelite
Leo Hendrik Baekeland, born on November 14, 1863, in Ghent, Belgium, invented Bakelite—the first fully synthetic plastic—in 1907. Baekeland was a Belgian-born chemist and entrepreneur who spent most of his career in the United States. He is often referred to as "The Father of the Plastics Industry".
Baekeland's interest in chemistry began early in his life, and he attended night classes in the subject while working as a pharmacist's assistant. He later enrolled at the University of Ghent on a city scholarship and graduated with a B.S. in chemistry in 1882. He received his doctorate maxima cum laude from the same university in 1884, at the young age of 21. Baekeland then taught at the University of Ghent until 1889, when he moved to the United States and joined a photographic firm.
In the US, Baekeland continued his work in chemistry and invented Velox, an improved photographic paper that could be developed using artificial light. This invention earned him a substantial amount of money, which he used to set up his own well-equipped laboratory. There, he began his search for a synthetic substitute for shellac, which at the time was made from the shells of Asian lac beetles. This endeavour ultimately led him to the discovery of Bakelite.
Through his experiments with phenol and formaldehyde, Baekeland first produced Novolak, a soluble phenol-formaldehyde shellac that was not a commercial success. He then focused on developing a phenol-formaldehyde binder for asbestos. By carefully controlling the pressure and temperature applied to these reagents, he successfully created Bakelite, a hard, mouldable plastic. This plastic was made from phenol (then known as carbolic acid) and formaldehyde, and it marked the beginning of the modern plastics industry.
Bakelite had numerous applications and was soon in high demand, especially in the rapidly growing automobile and radio industries. It was used to make a variety of products, including colourful objects such as jewellery, telephones, radios, and billiard balls. Radios, telephones, and electrical insulators were particularly well-suited for Bakelite due to its excellent electrical insulation and heat resistance.

The process of creating Bakelite
Belgian-born chemist Leo Baekeland invented Bakelite, the first fully synthetic plastic, in 1907. He is often referred to as "The Father of the Plastics Industry".
Baekeland's initial intention was to find a replacement for shellac, a material in limited supply as it was made from the secretion of lac insects. He first produced a soluble phenol-formaldehyde shellac called Novolak, which was unsuccessful in the market. He then began experimenting with strengthening wood by impregnating it with a synthetic resin.
Baekeland's creation of Bakelite involved combining phenol, also known as carbolic acid, and formaldehyde, derived from coal tar and wood alcohol (methanol) respectively. This chemical combination, known as a condensation reaction, was first reported in 1872 by German chemist Adolf von Baeyer, but Baekeland was the first to successfully control the reaction to produce a synthetic resin.
- Phenol and formaldehyde are heated in the presence of a catalyst such as hydrochloric acid, zinc chloride, or ammonia.
- This creates a liquid condensation product, referred to as Bakelite A, which is soluble in certain solvents like alcohol and acetone.
- The liquid resin can then be combined with fillers such as wood flour, asbestos fibres, cotton, or powdered bronze to form a mouldable compound.
- The compound is then heated and pressurised in a mould, forming a hard, infusible, and chemically resistant plastic.
By carefully controlling the pressure and temperature applied during the process, Baekeland was able to produce a durable and mouldable plastic with excellent electrical insulation and heat resistance. This made Bakelite suitable for a wide range of applications, from electrical insulators and radio knobs to colourful costume jewellery.

The impact of Bakeland's invention
In the early 1890s, Leo Baekeland, a Belgian-born chemist, began experimenting with synthetic materials. In 1907, he invented a new material called Bakelite, which is often credited as the world's first synthetic plastic. Bakelite was a significant invention with a profound and lasting impact on the world.
The invention of plastic revolutionized the way we interact with the world around us. Before plastic, materials such as wood, metal, glass, and natural fabrics were primarily used, but these materials had limitations. Wood could rot, metal could rust, glass could break, and natural fabrics could be expensive and time-consuming to produce. Plastic offered a cheap, durable, and versatile alternative. It could be molded into various shapes, making it suitable for a wide range of applications, from household goods to industrial products. Plastic's durability and low cost made it accessible to the masses, and it quickly became an integral part of people's daily lives.
