Abstract: The compound 2-hydroxy-5-oxoproline salt can be used to produce an increase in carbon dioxide fixation, growth, dry weight, nutritional value (proteins and amino acids), nodulation and nitrogen fixation and photosynthetically derived chemical energy when applied to plants through their roots and/or through their foliar portions. The embodiments provide an improved chemical synthesis for this compound which is performed in a single step reaction using ozone with 2-pyrrolidone-5-carboxylic acid. The steps of dissolving Sodium 2-pyrrolidone-5-carboxylate in aqueous solution and reacting a molar excess of ozone with the aqueous solution of sodium 2-pyrrolidone-5-carboxylate at a temperature between 20° C. and 100° C. can be carried out such that sodium 2-hydroxy-5-oxoproline salt is formed.

Abstract: One or more embodiments relate to a method for making carbon electrode material (CEM) having the steps: dispersing a carbon feedstock within a catalyst, thereby forming a mixture, wherein the catalyst is made up of particles; melting the carbon feedstock that is dispersed within the catalyst, thereby liquifying the carbon feedstock that coats catalyst particles and infiltrates spaces between the catalyst particles; carbonizing the melted carbon feedstock, thereby forming an interconnected 3D network of carbon nanosheets; converting the carbon nanosheets into graphene nanosheets; washing the graphene nanosheets, thereby forming the CEM; recovering and regenerating the catalyst. Further embodiments relate to repeating the method using recovered and regenerated catalyst.

Abstract: A process for the transesterification of methyl-2-ethylhexanoate with triethylene glycol to produce triethylene glycol di-2-ethylhexanoate is provided. In the process, methyl-2-ethylhexanoate is combined with triethylene glycol to form a first mixture. The first mixture is heated in the presence of a catalyst to form a second mixture comprising methanol and triethylene glycol di-2-ethylhexanoate. Methanol is separated from the second mixture to yield triethylene glycol di-2-ethylhexanoate. Na2CO3, Cs2CO3, K2CO3, Rb2CO3, sodium methoxide or titanium isopropoxide are suitable catalysts.
