CO Route Cuts Acrylic Acid Costs BEST INNOVATION BY AN SME since the 1980s but, to date, no one has been able to develop an economically feasible proc- ess. The thermoplastic has similar properties to polyethylene terephthalate (PET), but with significantly higher barrier properties. Novomer’s proprietary system is based on ho- mogeneous catalyst technology that was origi- nally discovered at New York-based Cornell University by Geoffrey Coates, Novomer’s co-founder and chairman of its scientific advisory board. The significance of the process is that it enables the use of a low-cost monomer, in this case carbon monoxide (CO), which is combined with ethylene oxide (EO) to make propriolactone. Novomer says that the use of inexpensive raw materials, such as CO and ethane-derived EO, and the catalyst’s selec- Superabsorbent polymer (SAP) made with Novomer’s catalyst has the same tivity, which is in excess performance as SAP made using the traditional propylene-based route of 99%, means that the Novomer “Our ultimate vision... is that low molecular weight PPL CO route could be shipped globally and converted to AA or acrylate esters upon demand” MIKE SLOWIK cuts acrylic Director of chemicals, Novomer cost of the process is potentially 40% lower than current available technologies. acid costs In addition, the process is expected to have a lower carbon and energy footprint because it operates at moderate temperatures, notably between 30-50oC.

  • Rheology Modification of Hydrogen Peroxide-Based Applications Using
    Rheology Modification of Hydrogen Peroxide-Based Applications Using Cross-Linked Polyacrylic Acid Polymers* Julie Schmucker-Castner and Dilip Desai The BFGoodrich Company 1. Key Words: Hydrogen Peroxide, Hair Bleach, Two-Part Hair Color, Rheology Modification, Thickened Hydrogen Peroxide, Hydrogen Peroxide Gels, Hydrogen Peroxide Stability, Cross-Linked Polyacrylic Acid, Carbomer, Acrylates / C10-30 Alkyl Acrylate Crosspolymer 2. Summary: A fundamental study of the stability of hydrogen peroxide-based gels, thickened using cross-linked polyacrylic acid polymers, will be presented. Recent systematic experiments will demonstrate that excellent long-term stability of such gels can be achieved. The study evaluates different types of cross- linked polyacrylic acid polymers (as well as an associative acrylic polymer), several commercial sources of hydrogen peroxide, hydrogen peroxide concentrations and the effect of pH. Resulting viscosities from combinations of these variables will be presented, as well as the effects of accelerated aging on percent active peroxide and viscosity of the thickened peroxide gels. The results of this study will enable the formulator to determine the appropriate polymer and conditions necessary for optimal stability and rheological properties for hydrogen peroxide applications. This study will demonstrate that some cross-linked polyacrylic acid polymers are very compatible and stable with H2O2 and that these polymers do not affect the H2O2 stability under certain conditions. In addition, this study will show that certain cross-linked polyacrylic acid polymers can produce very viscous gels and yield higher viscosities in typical permanent hair color formulas compared to many commercially available products. Because of the excellent compatibility and stability demonstrated, cross-linked acrylic acid polymers are ideal rheological modifiers for hydrogen peroxide-based applications.

Propane to Acrylic Acid Abstract Acrylic acid is an essential polymer raw material for many industrial and consumer products. Currently, acrylic acid is manufactured from propylene, which is created as a by- product from fossil fuels manufacture and industrial cracking of heavy hydrocarbons. However, the discovery of new natural gas reserves presents new opportunities for the production of acrylic acid. A design feasibility study is presented to analyze the economics behind producing acrylic acid from the selective oxidation of propane to propylene over a mixed metal oxide catalyst, Mo1V0.30Te0.23Nb0.125Ox. The proposed plant is located in the U.S. Gulf Coast and produces 200MM lb/yr acrylic acid. Since the catalytic oxidation process has low propane conversion per pass, the process recycles unconverted propane and propylene back to the reactor to increase overall conversion. The acrylic acid is then separated and purified ot the glacial-grade industrial standard for polymer raw material of 99.7% acrylic acid by mass.

The polymerizable monomer was polymerized without solvent to prepare viscous poly ionic liquid as AMPS/AA-QA. The chemical structure and thermal characteristics of AMPS/AA-QA were investigated by NMR, DSC and TGA. The wetting characteristics of AMPS/AA-QA were measured at the steel surface by measuring the contact angles. This work describes the successful performance of AMPS/AA-QA as eco-friendly corrosion inhibitors for steel in acidic chloride solution. Corrosion inhibition of steel was carried out by electrochemical techniques. The experimental results reveal that AMPS/AA-QA is efficient mixed type corrosion inhibitors. Inhibition efficiency of 93.7% is reached with 25ppm of AMPS/AA-QA.

Pericosines show significant in vitro cytotoxicity against P388 lymphocytic leukemia cells. Pericosine A, in particular, shows the most potent activity and significant in vivo antitumor activity against P388 cells. Thus, pericosines are promising candidates for seed compounds of anticancer drugs. However, before the total syntheses of pericosines were accomplished, their stereo structures could not be determined by spectral analyses because they have multi- functionalized cyclohexenoid structures with torsional strain. In this review, synthetic efforts for pericosines in this decade are surveyed. Keywords: marine natural product, antitumor, pericosine, structure determination, total synthesis, carbasugar 1. Introduction Synthetic studies of carbasugars have been progressing on a worldwide scale [1-3]. Carbasugars are a class of carbocyclic analogues of monosaccharides in which oxygen atom in the ring is replaced with a carbon atom. Because of this, they are also called pseudo-sugars. Carbasugars exhibit gycosidase inhibitory, antitumor (including anticancer), antiviral, antifungal, antibacterial, and antimalarial activities.
