A method for converting vanillin to bis(cyanate) ester monomers, comprising treating vanillin with a reductive coupling agent to form at least one olefin. The olefin or olefins are treated with hydrogen and a metal catalyst to hydrogenate said olefin. The hydrogenated olefin or olefins are treated with at least one cyanogen halide and a base in an organic solvent to afford at least one olefin monomer. The olefin monomer or monomers are purified by recrystallization or precipitation from an organic solvent.

Polymeric materials made from vanillin

A formulation and methods for making high energy organic fuels that incorporate suspended metal particles with metal particle sized ranging from 33 nm to 5 micron. The hybrid organic fuels contain superior density and/or energy content to conventional liquid organic fuels. These hybrid organic fuels used in combination with metal particle afford fuels with 5 to 80% more net heat of combustion (based on volume). These fuels should extend the distant range for jets, liquid rocket engines, SCRAM jet engines, and improve energy content in fuel-air explosive applications such as fuel-air explosives and in the Multi-Effects Weapons System (MEWS) where the fuel is used both for propulsion and explosive effects.

Hybrid metallized organic fuels

The present invention provides a pigment/additive comprising discrete multivalent oxidation state (DiMVO) phenothiazine compounds having corrosion inhibiting properties. These novel DiMVO phenothiazines are useful in preparing waterborne primer coating formulations for application to metals and metal alloys and demonstrating corrosion inhibiting properties. Furthermore, such formulations are chromate-free and have reduced VOC content. Methods of preparing and using such compounds and waterborne formulations also are described.

An improved process and apparatus for the selective reaction of terpenes (including mono-, sesqui-, di-terpenes, and others in the terpene family), alpha-olefin oligomers (OOA's), and related olefins to their respective dimeric product in high purity using heterogeneous acid catalyst concurrent with full utilization of energy created in the process. Embodiments of the invention carry out a unique and highly efficient dimerization of terpenes, alpha-olefin oligomers (OOA's), and olefins using cost effective catalysts and low cost equipment that are ideally suited for commercialization of jet/turbine and diesel biofuel processes producing fuels with high flashpoints and superb cold flow properties.

Acyclic monterpene alcohols, like linalool, to be converted through a series of highly efficient catalytic reactions a biogasoline blending component, and a drop-in biodiesel fuel.

A vanillin is found to be a useful starting material for preparing new monomers that can be further applied to make high Tg composite resins that are in turn useful for making composite parts.

A renewable biofuel based on a highly efficient batch catalysis methodology for conversion of 1-butene to a new class of potential jet fuel blends. By tuning the catalyst and then using the dimer produced, the carbon use is about 95% or greater. This latter point will be particularly important in the future, where the source of raw materials (i.e., biomass/biofeedstock) is limited.

Diesel and jet fuels based on the oligomerization of butene

A method and apparatus for dehydrating bio-1-alcohols to bio-1-alkenes with high selectivity. The bio-1-alkenes are useful in preparing high flashpoint diesel and jet biofuels which are useful to civilian and military applications. Furthermore, the bio-1-alkenes may be converted to biolubricants useful in the transporation sector and other areas requiring high purity/thermally stable lubricants.

Process for the dehydration of aqueous bio-derived terminal alcohols to terminal alkenes

A method for the selective synthesis of bisphenols, thermosetting resins, and thermoplastics from salicylic acid, the major component of wintergreen oil, and a viable target for engineered biosynthesis. Condensation of salicylic acid, structural analogs of salicylic acid, and derivatives of salicylic acid with short chain aldehydes or ketones and subsequent decarboxylation has the potential to produce bisphenols that are direct replacements for conventional resins, while the steric and electronic effects of salicylic acid improve the efficiency and selectivity of the conversion process. The utilization of renewable polyphenols as precursors to epoxies, poly carbonates, and high temperature thermosets including cyanate esters, provides an opportunity to develop full-performance resins while reducing the use of petroleum based feedstocks. This approach will then diminish the overall environmental impact of resin production while allowing for a sustainable source of phenols.

A composition and method of preparing and adding unique organic additives to a metal-free coating system followed by application then provides long term corrosion protection to a reactive metal surface.

A class of modified single-ring cyanate esters which have shown the ability to tailor and control the glass-transition (Tg) of the cured resins as well as the water uptake.
