Usage

General Description

Calcium ethoxide is a chemical compound commonly used as a catalyst in organic synthesis and as a strong base in chemical reactions. It is an organometallic compound with the formula Ca(C2H5O)2 and is typically a white, powdery solid. Calcium ethoxide is highly reactive and can easily react with moisture in the air to form calcium hydroxide and ethanol. It is commonly used in the production of certain types of plastics, pharmaceuticals, and as a reagent in organic synthesis. Due to its reactive nature, it must be handled and stored with care, as it can present fire and explosion hazards.

Convenient two step synthesis of29Si labelled tetraalkoxysilanes

29Si enrichment would be advantageous for many NMR studies of the structural properties of sol-gel derived materials. The required starting materials (29Si enriched alkoxysilanes), however, are expensive and difficult to provide. Here we present a scalable, reliable synthesis of 29Si enriched tetraethoxysilane starting from silicon dioxide or elemental silicon with a total yield up to 75%.

Alkoxy metal powder as well as preparation method and application thereof

The invention relates to a preparation method and an application of alkoxy metal powder, which are applied to preparation of an alkoxy metal carrier of an olefin polymerization catalyst. The alkoxy metal carrier comprises the following components: metal halide, sodium alcoholate or potassium alcoholate, or a solvent. The molar ratio of the components for preparing the alkoxy metal compound is as follows: metal halide: sodium alcoholate or potassium alcoholate = 1:(0.001-30); wherein the metal halide is a metal chloride, a metal bromide, a metal fluoride or a metal iodide; the metal is a main group metal, a sub-group metal or a VIII group metal. The catalyst prepared from the carrier is used for preparing an olefin polymerization catalyst, and has the advantages of high catalyst activity, good hydrogen regulation performance, good copolymerization performance, low polymer powder content, low wax content and good particle morphology; the catalyst is used for ethylene homopolymerization,ethylene and alpha-olefin copolymerization or ethylene and polar alkene monomer copolymerization, propylene homopolymerization, propylene and alpha-olefin copolymerization, or propylene and polar alkene monomer copolymerization.

Study of challenging calcium alkoxides in solution by electrospray ionization mass spectrometry (Part 1)

Electrospray ionization was applied on calcium alkoxides studying the most suitable operative conditions for their detection/identification. To reach this aim, calcium methoxide and ethylate were obtained by two different synthetic pathways, in order to understand their possible different aggregation states. The reaction mixture shows the presence of a supernatant and of a precipitate poorly soluble in most organic solvents. The purpose of this preliminary study is to understand the qualitative differences between the precipitated species and the ones in solution by analyzing both of them with the same analytical method. The electrospray ionization (ESI) operating conditions (voltages, temperatures, solvents) allow not only the detection of single species but also the study of clusters present in solution. Particular attention was paid to establishing the role of ESI conditions in the formation of the detected species. Experiments performed at different sprayer voltages (1 kV, 2 kV, 3 kV and 4 kV) proved that ESI does not perturbate the equilibria present in the original solution, demonstrating that the technique can be a useful tool to achieve information on this class of compounds.
