Uses

Used in Analytical Chemistry:
4-METHYLHEPTANE is used as a reference substance for identifying volatile organic compounds (VOCs) in the headspace of cultures containing different MAP strains. This is achieved through the use of solid phase micro extraction and gas chromatography/mass spectrometry (SPME-GC-MS) techniques, which allow for the accurate detection and quantification of VOCs.
Used in Organic Synthesis:
4-METHYLHEPTANE serves as an important intermediate in the synthesis of various organic compounds. Its unique structure and reactivity make it a valuable building block for the production of pharmaceuticals, agrochemicals, and other specialty chemicals. The branched-chain alkane can be used in reactions such as alkylation, acylation, and substitution, enabling the formation of a wide range of organic molecules.

GASOLINE PREPARED FROM BIOMASS-DERIVED LEVULINIC ACID

The present invention provides methods for preparing a C6-C10 alkane, and mixture thereof. The methods include forming a reaction mixture containing an angelica lactone dimer, a catalyst, and a hydrogen source under conditions sufficient to reduce the angelica lactone dimer, thereby preparing the alkane. The methods can be used to prepare branched alkanes useful for fuels. Methods for preparing an angelica lactone, methods for preparing an angelica lactone dimer, and methods for reducing a lactone to an alkane are also described.

Hydrodeoxygenation of the angelica lactone dimer, a cellulose-based feedstock: Simple, high-yield synthesis of branched C7-C10 gasoline-like hydrocarbons

Dehydration of biomass-derived levulinic acid under solid acid catalysis and treatment of the resulting angelica lactone with catalytic K 2CO3 produces the angelica lactone dimer in excellent yield. This dimer serves as a novel feedstock for hydrodeoxygenation, which proceeds under relatively mild conditions with a combination of oxophilic metal and noble metal catalysts to yield branched C7-C10 hydrocarbons in the gasoline volatility range. Considering that levulinic acid is available in >80 % conversion from raw biomass, a field-to-tank yield of drop-in, cellulosic gasoline of >60 % is possible. Fuel for thought: Biomass-derived levulinic acid can be converted in three simple steps via the angelica lactone dimer into branched, gasoline-range hydrocarbons in high yield by using a combination of oxophilic metal and noble metal catalysts (see scheme).

Impact of cationic surfactant chain length during SAPO-11 molecular sieve synthesis on structure, acidity, and n-octane isomerization to di-methyl hexanes

The structure, acidity, and n-octane di-branched isomerization of SAPO-11 synthesized with surfactants of different chain lengths in water-propanol system were investigated. The results showed that with the increasing chain length of surfactants, the crys

Ring opening of decalin via hydrogenolysis on Ir/- and Pt/silica catalysts

The catalytic conversion of cis-decalin was studied at a hydrogen pressure of 5.2 MPa and temperatures of 250-410 °C on iridium and platinum supported on non-acidic silica. The absence of catalytically active Br?nsted acid sites was indicated by both FT-IR spectroscopy with pyridine as a probe and the selectivities in a catalytic test reaction, viz. the hydroconversion of n-octane. On iridium/silica, decalin hydroconversion starts at ca. 250-300 °C, and no skeletal isomerization occurs. The first step is rather hydrogenolytic opening of one six-membered ring to form the direct ring-opening products butylcyclohexane, 1-methyl-2-propylcyclohexane and 1,2- diethylcyclohexane. These show a consecutive hydrogenolysis, either of an endocyclic carboncarbon bond into open-chain decanes or of an exocyclic carboncarbon bond resulting primarily in methane and C9 naphthenes. The latter can undergo a further endocyclic hydrogenolysis leading to open-chain nonanes. All individual C10 and C9 hydrocarbons predicted by this direct ring-opening mechanism were identified in the products generated on the iridium/silica catalysts. The carbon-number distributions of the hydrocracked products C9- show a peculiar shape resembling a hammock and could be readily predicted by simulation of the direct ring-opening mechanism. Platinum on silica was found to require temperatures around 350-400 °C at which relatively large amounts of tetralin and naphthalene are formed. The most abundant primary products on Pt/silica are spiro[4.5]decane and butylcyclohexane which can be readily accounted for by the well known platinum-induced mechanisms described in the literature for smaller model hydrocarbons, namely the bond-shift isomerization mechanism and hydrogenolysis of a secondary-tertiary carboncarbon bond in decalin.

Alkene oligomerization process

A process for oligomerising alkenes having from 3 to 6 carbon atoms which comprises contacting a feedstock comprising a) one or several alkenes having x carbon atoms, and, b) optionally, one or several alkenes having y carbon atoms, x and y being different, with a catalyst containing a zeolite of the MFS structure type, under conditions to obtain selectively oligomeric product containing predominant amounts of certain oligomers. The process is carried out at a temperature comprised between 125 and 175° C. when the feedstock contains only alkenes with 3 carbon atoms and between 140 and 240° C., preferably between 140 and 200° C. when the feedstock contains comprises at least one alkene with 4 or more carbon atoms.

Pt/SAPO-5 and Pt/SAPO-11 as Catalysts for the Hydroisomerization and Hydrocracking of n-Octane

n-Octane hydroisomerization and hydrocracking on SAPO-5 and SAPO-11 catalysts containing 0.5 wt.percent Pt have been investigated in a flow reactor over a wide range of temperatures (573-708 K) and pressures (atmospheric, 3 and 5 bar).These studies have shown that hydroisomerization is a function of the total conversion.The primary products obtained with n-octane were the monobranched isomers.Multibranched feed isomers and cracked products were formed in subsequent reactions.In all cases, hydrogen pressure had a strong influence on the activity and time-on-stream deactivation.Hydroisomerization can be considered to be the primary reaction, with hydrocracking occurring to a significant extent only at higher conversions (>40percent for Pt/SAPO-5 and >65percent for Pt/SAPO-11).The selectivity patterns found in these molecular-sieve catalysts are interpreted in terms of a series of reaction pathways incorporating both confinement effects and shape selectivity factors.
