COMPOUNDS FROM RENEWABLE RESOURCES

Compounds of formula III: This application claims priority to U.S. Provisional Application No. 62/320,087 that was filed on Apr. 8, 2016. The entire content of the application referenced above is hereby incorporated by referenced herein.Itaconic acid (or itaconate, depending on its prevailing ionization state; Medway, A. M., Sperry, 2014, 16, 2084-2101) and furfural (Cai, C. M., et al., 2014, 89, 2-10) are two chemicals abundantly available from biomass. They are prominent entries on master lists of privileged compounds for potential use in preparing bio-sourced/sustainable/renewable polymers and materials (e.g., Ritter, S. K., Chem. 2004, 82, 31-34; Top value added chemicals from biomass, Volume I-Results of screening for potential candidates from sugars and synthesis gas. eds. Werpy T., Petersen, G., US Department of Energy, 2004. nrel.gov/docs/fy04osti/35523.pdf (accessed Jan. 15, 2016)). The first arises by metabolic pathways as textbook as the citric acid (also known as the tricarboxylic or Krebs) cycle; the second by acid-catalyzed dehydration of 5-carbon sugars prevalent in, for example, corncobs (Adams, R., Voorhees, V., , Vol. 1, 1921, 49) and oat husks. For a century it has been known that each of itaconic anhydride (1, IA) and furfuryl alcohol (2, FA) is readily available by simple conversions such as dehydration (Fittig R., et al., 1904, 331, 151-196) and reduction (Kaufmann W. E., Adams, R., 1923, 45, 3029-3044) of these abundantly available precursors (Scheme 1).The Diels-Alder (DA) [4+2] cycloaddition reaction to produce cyclohexene derivatives is among the most iconic of all reactions in organic chemistry. The ability of IA to function as a dienophile, the 2π-component, to engage various dienes was, in fact, described in the ground-breaking first publication by Diels and Alder (Diels O., Alder K., 1928, 460, 98-122). The use of furan as a diene, the 4π-component, was reported one year later in their second paper on the subject of “hydroaromatic ...

Improvements in or relating to the regeneration of olefins from acid solutions

Mono-olefins of 2-6 carbon atoms are recovered from an acid extract thereof containing the corresponding alcohols or acid esters by passing the extract, diluted if necessary, in the form of one or more streams of a length of the order of 3-10 feet into a decomposition zone surrounded by a heat-exchange surface, the cross-sectional area of the stream being such that no particle is substantially more than 3/8 inch from a heat-exchange surface, maintaining the stream at a substantially uniform temperature between 130 DEG and 295 DEG C., causing decomposition by flash vaporization to mono-olefin vapour, water vapour, and liquid acid, continuously passing the stream of vapour and liquid through the decomposition zone, and rapidly removing and separating the same.

PROCESS FOR PREPARATION OF HIGH PURITY ISOBUTYLENE

ABSTRACT OF THE DISCLOSURE Highly purified isobutylene, up to 99.9% pure, is obtained by treating a reaction mixture such as that recovered from an isobutylene-containing hydrocarbon mixture also containing an aqueous solution of an aliphatic carboxylic acid having 1 to 6 carbon atoms that has been reacted in an acidic ion exchanger and from which the unreacted hydrocarbons have been removed. The operative ingredients of the treated mixture are tertiary butyl alcohol, secondary butyl alcohol and their esters of the carboxylic acid employed. When treated with an acidic ion exchanger the carboxylic acid is first formed which inhibits the secondary butyl alcohol and secondary butyl ester of the acid from decomposing and high purity isobutylene is recovered therefrom by conventional distillation.

Manufacture of butadiene

Butadiene is produced by heating a mono-or diester of 2-3 butylene glycol with a monocarboxylic acid, which may be aliphatic or aromatic. Suitable acids are formic, acetic, propionic, butyric, isobutyric, benzoic, and o- and p-toluic acids. Suitable esters are the mono-ester of acetic acid, and the di-esters of formic, acetic, propionic, and benzoic acids. The process may be effected by passing the vapour of the ester, with or without a diluent such as nitrogen or benzene through a heated tube which may be packed with quartz, earthenware rings, steel shavings, silica gel or active carbon. The temperature may be 475-600 DEG C. It is thought that the junction is effected in two stages, the first being the conversion of a diester to an a -methyl allyl ester and that the second stage does not readily take place below 475 DEG C. The glycol diacetate may be made by heating 2-3 butylene glycol with acetic acid, sulphuric acid, and benzene, the benzene being added to carry off the water during ...

Alpha olefins from lower alkene oligomers

Internally unsaturated near linear oligomers of lower olefins are converted into alpha olefins, or 1-alkenes, of essentially the same degree of linearity. The internally unsaturated olefins are the product of lower alkene oligomerization using a surface deactivated zeloite, such as ZSM-5 or ZSM-23, and contain about 1 to 2 methyl branches per twelve (12) carbon atoms. The feedstock is converted to alpha olefin oligomers which also contain approximately 1 to 2 methyl branches per thirteen (13) carbon atoms. The conversion is achieved by hydroformylation of the near linear internal olefins to provide a novel 1-alkanol oligomer structure without further branching of the carbon oligomeric chain. Acetylation of the 1-alkanol followed by deesterification by pyrolysis provides the sought for near linear 1-alkene. The near-linear oligomers of lower olefins so produced comprise vinyl hydrocarbon monomers that can be further oligomerized by cationic and coordination catalysts.
