Stay up to date and in-the-know on everything happening with Evonik Jayhawk and the Custom Manufacturing and Fine Chemical world.
WHAT IS A HIGH-PURITY SOLVENT?
High-purity solvents are synthetically-distilled organic chemicals with broad industrial applications. They are crucial for the synthesis of complex Grignard reactions in laboratory conditions and are... MORE
WHAT IS HYDROGENATION?
Hydrogenation is widely used in organic chemistry, typically for the conversion of unsaturated compounds to their saturated derivatives, with unsaturation defined as the presence of double or triple bonds within the molecule. In simple terms, hydrogenation is... MORE
WHAT IS BTDA®?
BTDA (3,3’, 4,4’-Benzophenonetetracarboxylicdianhydride) is a dianhydride that has been produced at the JAYHAWK site since the early 1970s. Since then it has grown into a flagship product with a proven performance edge in the fields of epoxy and polyimide chemistry.
BTDA is a thermal curative that can improve... MORE

JAYHAWK TO ATTEND TRFA ANNUAL MEETING 2018
The JAYHAWK team will attend the Thermoset Resin Formulators Association (TRFA) 2018 Annual Meeting, in Nashville Tennessee on March 11-14.
The TRFA was founded to aid thermoset resin manufacturers and their suppliers, with a broader focus than just epoxy chemistry. The TRFA also represents phenolics, acrylic, silicone, urethane, polyester, and vinyl ester systems.... MORE
WHAT IS SUZUKI COUPLING?
Suzuki coupling is a widely used cross coupling reaction between an organohalide and typically an orgaonoborinic acid. The reaction is typically catalysed by a Pd-based catalyst and runs under mild conditions. A wide variety of solvents can be used, including... MORE
WHAT IS A CROSSLINKER?
Crosslinking refers to the interconnecting or bridging of two chemical compounds, and a crosslinker is the molecule that is used to make this interconnection. Crosslinkers can be used for all types of polymeric materials, with the identification of the crosslinker being dependent on the application requirements.
Polymer crosslinking is accomplished via... MORE

WHAT IS SYNTACTIC FOAM?
A syntactic foam is a composite material that is made by filling a polymer, ceramic, or metal with pre-formed hollow glass or ceramic spheres called micro balloons. The term ‘syntactic’ refers to the ordered arrangement of the spheres, and the term ‘foam’ refers to the closed cellular structure.
Syntactic Foam Properties
The hollow spheres within syntactic foam provide most of the... MORE
WHAT IS A GRIGNARD REACTION?
A Grignard reaction is actually a two-step chemical reaction that consists of:
1. Formation of the Grignard reagent by reaction of Mg with an organohalide in a donor solvent.
2. Reaction of the Grignard reagent with a substrate.
The Grignard reaction was discovered in... MORE
JAYHAWK TO ATTEND 2018 HIGH TEMPLE WORKSHOP
The team at JAYHAWK are happy to announce that we’ll be attending the 2018 High Temple Workshop from January 29th to February 1st. This year the event is being held at... MORE
DIANHYDRIDES FROM JAYHAWK EVONIK
The term “dianhydride” describes a general class of fine chemical intermediate formed by the removal of water from an organic acid. The simplest example, two acyl groups bound by a common oxygen molecule, is shown... MORE
WHAT IS A POLYIMIDE?
A polymer is defined as a large network of molecules that consist of many repeat units. A polyimide is a specific type of polymer, consisting of imide monomers. Polyimides are highly desirable for their heat resistance, mechanical strength and insulative properties.
To obtain a good understanding of what a polyimide is, first... MORE
WHAT IS AN EPOXY?
An epoxy is a thermosetting polymer that possesses unique mechanical and resistance properties. The term epoxy can be used for the cured end product or any of the basic components within epoxy resins.
An epoxy resin is a class of... MORE
NEW WEBINAR DISCUSSES IMPROVING EPOXY SYNTACTIC FOAM PERFORMANCE AND PROPERTIES
The second webinar in a collaborative series between Evonik Jayhawk Fine Chemicals and Dixie Chemicals will outline how the companies are improving the properties of epoxy syntactic foams. The series focuses on epoxy syntactic foam technology, specifically for oil and gas applications, and the first webinar discussed... MORE
