Mixed C4 olefins (primarily iC4) are isolated from a mixed C olefin and paraffin stream. Two different liquid adsorption high-purity C olefin processes exist the C4 Olex process for producing isobutylene (iCf ) and the Sorbutene process for producing butene-1. Isobutylene has been used in alcohol synthesis and the production of methyl tert-butyl ether (MTBE) and isooctane, both of which improve octane of gasoHne. Commercial 1-butene is used in the manufacture of both hnear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE)., polypropylene, polybutene, butylene oxide and the C4 solvents secondary butyl alcohol (SBA) and methyl ethyl ketone (MEK). While the C4 Olex process has been commercially demonstrated, the Sorbutene process has only been demonstrated on a pilot scale. 

Another use of 1-butene is in the production of solvents containing four carbons such as secondary butyl alcohol and methyl ethyl ketone (MEK). Secondary butyl alcohol is produced by reacting 1-butene with sulfuric acid and then hydrolysis ... 

Methyl ethyl ketone (MEK boiling point 769.6°C, density 0.8062, flash point -6°C) is an important coating solvent for many polymers and is made by the sulfation and hydration of 1 or 2-butene to sec-butyl alcohol, which is then dehydrogenated to the ketone (Fig. 1). 

Preparation of Monomers. Methyl vinyl ketone (MVK) was obtained from Pfizer Chemical Division, New York, and distilled to remove the inhibitor. Methyl isopropenyl ketone (MIPK) was prepared by the aldol condensation of methyl ethyl ketone and formaldehyde, according to the method of Landau and Irany 0. The major impurity in this monomer is ethyl vinyl ketone (5. The monomer was redistilled before use. 3 Ethyl 3 buten 2 one (EB) was prepared by the aldol condensation of methyl propyl ketone and formaldehyde. Ethyl vinyl ketone (EVK) was prepared by a Grignard synthesis of the alcohol, followed by oxidation to the ketone. t-Butyl vinyl ketone (tBVK) was prepared from pinacolone and formaldehyde by the method of Cologne (9). Phenyl vinyl ketone (PVK) was prepared fay the dehydrochlorlnatlon of 0 cbloro propiophenone (Eastman Kodak). Phenyl isopropenyl ketone (PPK) was prepared by the Mannich reaction using propiophenone, formaldehyde and dimethylamine HCl. 

Table 10.9 lists the main economic data available on the production of methyl ethyl ketone from n-butenes, in two steps involving the intermediate formation of secondary butyl alcohol by sulfuric hydration followed by dehydrogenation, or directly by the Wacker/Hoechst technology.

The main uses of 1-butene, 1-hexene, and 1-octene are in the manufacture of linear low-density polyethylene (LLDPE) (see Section 6.1.1). Butene is also used in the manufacture of solvents such as methyl ethyl ketone or secondary butyl alcohol. Apart from LLDPE, 1-octene is used in the manufacture of isononyl alcohol (see Section 5.2).
