Product Stewardship Summary
RAFFINATE-1
This product stewardship summary is intended to give general information about the
chemical or categories of chemicals addressed. It is not intended to provide an in-depth
discussion of health and safety information. Additional information is available through
the chemical’s applicable Material Safety Data Sheet, which should be consulted
before use of the chemical. This product stewardship summary does not supplant or
replace required regulatory and/or legal communication documents.
A. Chemical Identification
Raffinate-1 is produced as a co-product of ethylene manufacture from a steam
cracker. The product is extracted from the crude C4 stream in a butadiene extraction
plant. The valuable butadiene which may be 40-45% of the stream, what is left is
Raffinate-1. It consists of Isobutylene, the two normal isomers, butene-1 and butene-2
and small quantities of butanes and other compounds. Removal of the isobutylene,
usually by reaction with Methanol to produce MTBE, leaves Raffinate-2.

B. Raffinate-1 Uses
Raffinate-1 is a chemical building block used in the manufacture of methyl tertiary
butyl ether (MTBE) and diisobutylene (DIB). MTBE is a liquid added to petroleum to
reduce emissions, and DIB is an intermediate in the production of alcohols and solvents
end uses include adhesives for the plastics industry, electrical insulating materials,
protective coatings, and sealing compounds.
C. Health, Safety and Environmental Information
Acute exposure results in irritation of the mucous membranes, higher levels can result
in neurological effects such as blurred vision, fatigue, headache and vertigo. Exposure to
the skin can lead to frostbite. Long-term exposure has been associated with
cardiovascular disease, there is a consistent association with leukemia, and weaker
association with other cancers.
Raffinate-1 is listed as a known carcinogen by the Agency for Toxic Substances
Disease Registry and the US EPA. The American Conference of Governmental Industrial
Hygienists (ACGIH) lists the chemical as a suspected carcinogen. The Natural Resource
Defense Council (NRDC) lists some disease clusters that are suspected to be associated
with this chemical.

Product Stewardship Summary
D. Storage and Transport
Storage of Raffinate-1 as a compressed, liquefied gas carries a specific and unusual
hazard. Steel is recommended for tanks and piping in Raffinate-1 service, and it is usually
stored under pressure or in insulated tanks at reduced temperature, preferably below
1.6°C.
E. Conclusion
Raffinate-1 is highly flammable. Acute toxicity is low at typical exposure levels.
High levels of exposure for short or long periods can cause eye, nose and throat irritation
headaches, and other reversible central nervous system effects ranging from dizziness to
unconsciousness. Raffinate-1 should be stored in mild steel or stainless steel. Control
measures have been put in place to minimize exposure potentials to workers, public, and
the environment. However, prior to use or handling Raffinate-1, make sure to consult the
relevant product Material Safety Data Sheet and review applicable regulatory guidelines
and requirements, including but not limited to OSHA guidelines, should be consulted
prior to the use or handling of Raffinate-1.
