The petro-chemical industry begins with the production of inexpensive raw materials that supersede the acetylene chemical industry:
The production of acetaldehyde is converted to use the raw material ethylene.
Dr. Georg Janning is named chairman of the Knapsack-Griesheim AG (corporation).
Chlorine, a new basic element used in the chemical industry, finds its way to Knapsack. Commissioning of the first production plant in the new works section Hürth takes place. A chloralkali-electrolysis process is used in this plant.
Phosphorus pentasulfide is Knapsack’s newest product and the manufacturing of carbon black is converted for the production of acetogen carbon black.
Conversion to ethylene based production for vinyl chloride.
The production of dicalcium phosphate, an abrasive agent in toothpaste, begins.
The detergent phosphate Thermphos NW is a further new product.
The merger of the works groups Oxygen and Griesheim-Autogen with ADOLF MESSER GMBH to become MESSER GRIESHEIM GMBH (Ltd.) takes place.
A cooperation with Krims-Chemie GmbH (Ltd.) in the Wachau is entered into, the so-called Krems-Knapsack Phorphorprodukte GmbH (Ltd.), in order to meet the demand for Austria’s and southern Europe’s phosphorus product demands.
Knapsack begins operating under the name KNAPSACK AKTIENGESELLSCHAFT on 1 January 1965
Further expansion of the works site in Hürth - the following plants begin operations:
- A phosphoric acid production plant, which uses a wet production process
- a plant that produces feed additives (HOSTAPHOS),
- a polyvinyl chloride plant
- and a central waste water treatment facility.
- The inorganic research team takes over a modern research laboratory on the Hürth site.
On 31 December 1966 Dr. Günther Breil succeeds Dr. Querengässer after his resignation as works manager until 31 March 1970. Dr Breil is appointed to the board of Knapsack AG (corporation) from 30 June 1967.

A joint venture between Johann Anton Benckiser GmbH (Ltd.) and Knapsack lead to the founding of the Benckiser Knapsack GmbH, Ladenburg. Benckiser renders its complete phosphate business (except for cleaning agents and brand name products) and Hoechst its phosphate sector in the company Albert.
The first phosphorus furnace (60 MW) using Knapsack’s know-how goes into production in Vlissingen (The Netherlands).
The production plant for vinyl acetate based on acetylene goes into service.
In starting operations of a company own ethylene pipeline between Kelsterbach and Wesseling in conjunction with the existing pipeline network Hoechst/Knapsack, the Frankfurt area is connected to the Ruhr region.
