7756-94-7 Usage

Uses

Used in Rubber Industry:
TRIISOBUTYLENE is used as a monomer in the production of butyl rubber, which is a type of synthetic rubber known for its excellent resistance to heat, aging, and oxidation. It is commonly used in the manufacturing of tires, seals, and gaskets.
Used in Oil Industry:
TRIISOBUTYLENE is used as an additive in the production of lubricating oils. It helps to improve the viscosity, thermal stability, and oxidation resistance of the oils, making them suitable for various industrial applications.
Used in Motor Fuel Industry:
TRIISOBUTYLENE is used as a component in the formulation of motor fuels. It contributes to the improvement of fuel performance, including increased octane rating, reduced emissions, and enhanced combustion efficiency.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

TRIISOBUTYLENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.

Health Hazard

May be harmful by inhalation, ingestion or absorption. May cause eye and skin irritation.

Fire Hazard

Special Hazards of Combustion Products: Emits toxic fumes upon decomposition.

Check Digit Verification of cas no

The CAS Registry Mumber 7756-94-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,5 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7756-94:
(6*7)+(5*7)+(4*5)+(3*6)+(2*9)+(1*4)=137
137 % 10 = 7
So 7756-94-7 is a valid CAS Registry Number.

Diisobutylene process

-

Page/Page column 2, (2008/06/13)

This invention is a process for producing diisobutylene from isobutylene. The process comprises first oligomerizing isobutylene to diisobutylene using a sulfonic acid-type ion exchange resin. The oligomerization step is followed by contacting the diisobutylene product with an adsorbent to remove sulfur impurities produced during the oligomerization step. The adsorbent is a large pore zeolite such as zeolite X and zeolite Y. Optionally, the purified diisobutylene may be hydrogenated to isooctane using a hydrogenation catalyst.
