A microgel of a dz = 76 nm which is suitable for coupling with proteins, can be prepared by emulsion terpolymerization of NjAT -tetramethylene bisacrylamide, n-hexylmethacrylamide and propene acid amide-N-(4-methyl-2-butyl-1,3-diox-olane) [291 ]. The diameter of these microgels may be varied by the concentration of the emulsifier (Fig. 57) and is rather uniform. As the CMC of this system is about 2.5 X10"3 mol SDS/1, it may be assumed that below this value the copolymerization essentially takes place in the monomer droplets, whereas at higher concentrations of SDS preferentially the monomers in micelles are polymerized. [Pg.219]

The acid-base features of the catalysts were studied by the reaction of isopropanol conversion to propene (acidic feature) and acetone (basic feature) under N2 in the feed and the redox features by the reaction under air in the feed. It was observed at 230°C (table 4 from ref 40) that the pyrovanadate sample was much more basic than the other two pure phases and that excess MgO with respect to crystallized phase stoichiometry induced even more basic character (table 4). [Pg.72]

METHYL PROPENIC ACID, METHYL ESTER (80-62-6) CsHgOj Highly flammable, polymerizable liquid. Forms heat-sensitive explosive mixture with air [explosion limits in air (vol %) 1.8 to 12.5 flash point 50°F/10°C autoignition temp 790°F/421°C Fire Rating 3]. Unless inhibited, forms unstable peroxides heat or contaminants can cause explosive polymerization. Violent reaction with strong oxidizers benzoyl peroxide or other polymerization initiators.

METHYL PROPENIC ACID (79-41-4) Combustible liquid (flash point 152°F/67°C oc). A reducing agent. Violent reaction with oxidizers, strong acids, alkalis. Unless inhibited (100 ppm of the monomethyl ether of hydroquinone is recommended), can polymerize violently. Polymerization can be caused by elevated temperatures, peroxides, sunlight, or hydrochloric acid. Incompatible with ammonia, amines, isocyanates, alkylene oxides, epichlorohydrin. Attacks metals, natural rubber, neoprene, nitrile, and some plastics including PVC and polyvinyl alcohol. The uninhibited monomer vapor may block vents and confined spaces by forming a solid polymer material. [Pg.800]

METHYL PROPENIC ACID, METHYL ESTER (80-62-6) Forms heat-sensitive explosive mixture with air (flash point 50°F/10°C). Unless inhibited, forms unstable peroxides. Violent reaction with strong oxidizers, benzoyl peroxide, or other polymerization initiators. [Pg.800]

PROPENIC ACID, 2-METHYL-, BUTYL ESTER (97-88-1) Forms explosive mixture with air (flash point 105°F/41°C). Unless inhibitor is maintained at the proper level, oxidizers, heat, UV light, or moisture may cause polymerization. Reacts with oxidizers. May accumulate static electrical charges may cause ignition of its vapors. [Pg.1018]

Some natural fatty acids contain a carbocyclic unit which may have three (cyclopropane and cyclo-propene acids), five (prostaglandins-see Section 1.4 and cyclopentene acids) or six carbon atoms (cyclohexane acids). Aspects of this topic have been reviewed (Christie, 1970 Lie Ken lie, 1979 and Badami and Patil, 1982). Other cyclic acids occur in tall oil (Section 3.3.36). [Pg.18]

Around 110 megatons (Mt) of CO2 are annually used in commercial synthesis processes, to produce urea, salicylic acid, cyclic carbonates, and polycarbonates. The largest use is for urea production, which reached around 90 Mt/yr in 1997. In addition to these applications, there are a number of promising reactions currently under study in various laboratories, reactions that differ in the extent to which CO2 is reduced during the chemical transformation. They include the synthesis of commodities and intermediates (acetic acid, methanol, carbonates, cyclic carbonates, and lactones), polymers (polyurethanes, polypyrones) and a variety of functionalized carboxylic acids (propenic acid, 3-hexen-l,6-dioic acid). A more detailed description can be found in the cited review. ... [Pg.894]
