  • Patent number: 8163856
    Abstract: In an embodiment, a method is disclosed to increase the activity of an ionic liquid catalyst comprising emulsifying the ionic liquid catalyst with one or more liquid components. In an embodiment, a method is disclosed comprising introducing into a reaction zone a monomer feed and a reduced amount of ionic liquid catalyst and controlling an amount of shear present in the reaction zone to maintain a desired conversion reaction of the monomer. In an embodiment, a catalyzed reaction system is disclosed comprising a reactor configured to receive one or more liquid components and ionic liquid catalyst; a device coupled to the reactor for adding high shear to the liquid components and ionic liquid catalyst; and a controller coupled to the device for adding high shear and configured to control the amount of shear added to a catalyzed reaction zone to maintain a conversion reaction.

  • Patent number: 6339177
    Abstract: A vinyl monomer inhibitor systems is disclosed which includes 2,6-dinitro-4-alkylated phenols and mixtures of 2,6-dinitro-4-alkylated phenols and 2,4-dinitro-6-alkylated phenols as well as vinyl monomer stabilized composition including an effective amount of the inhibitor systems. A method for the preparation and use is also disclosed where phenol is first alkylated under conditions that afford predominately monoalkylated phenols having a high para alkylation preference, followed by nitration of the alkylated phenols to form a dinitrated, monoalkylated product.

  • Patent number: 4277520
    Abstract: The strength of ice is reduced by dissolving in water prior to freezing a composition of (A) a water-soluble polyhydroxy compound or monoalkylether thereof and (B) an alkali metal carbonate in an amount to provide an effective amount of (A) plus (B). The method is especially useful for application to particulate solids, such as coal and mineral ores, which are shipped and stored in masses exposed to freezing temperatures. Any ice that is formed is physically weak and will not deter the unloading of the thusly conditioned particulate solids.

  • Patent number: 4241216
    Abstract: A continuous process for the preparation in at least one esterification reactor of phthalate diesters utilizing phthalic acid or anhydride and a stoichiometric excess of at least one saturated aliphatic alcohol containing about 4 to about 10 carbon atoms comprises (a) reaction of phthalic acid or anhydride with said alcohol in a reactor zone, (b) purification of the diester in a purification zone in which the reaction product is neutralized with an alkali metal hydroxide, i.e., sodium hydroxide, to separate the diester and the unreacted phthalic acid or anhydride together with said saturated alcohol utilized in the reaction, said reaction product is separated into an organic phase and an aqueous waste phase.
