Sustainable application of calcium carbide residue as a filler for 3D printing materials

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Март 17, 2023

Industrial activity results in ton-scale production of calcium carbide and generation a significant amount residue (CCR), which is often disposed the environment as waste. CCR an active chemical, rain washes away alkali from sludge, changing pH soils water damaging environment. In this work, we explored new opportunities for utilization view coming industrial uptake digital design additive technologies. Amazingly, can be successfully used filler modification 3D printed materials towards introduction hybrid organic/inorganic frameworks. A series commercially available plastics (PLA, ABS, Nylon, PETG, SBS) were matrices CCR-based composite with high contents up to 28%. Tensile analyses showed increases tensile strength Young's modulus 9% 60%, respectively. Moreover, comparison pure plastics, better maintained digitally designed shape (lower shrinkage). Importantly, CCR-filled are printable, making them very promising components building sector. Considering already stored environment, material large quantities near future materials, anticipated exist manufacturing The involvement practical equally important environmental protection reuse multiple-ton wastes.

Calcium carbide residue — a key inorganic component of the sustainable carbon cycle

Russian Chemical Reviews, Год журнала: 2022, Номер 91(7), С. RCR5048 - RCR5048

Опубликована: Апрель 21, 2022

The transfer of waste materials from the chemical industry to building sector is an emerging area sustainable development. Leftovers, by-products, tails and sludge processes may be valuable components mixtures. Feeding construction by wastes a profitable chain for both sectors. In fact, calcium carbide residue (CCR) can considered link between materials. Carbide main product acetylene gas production carbide. released actively used in modern industry. An alternative method — cracking oil beyond sustainability; thus, route more promising hydrocarbon-free future. However, accompanied significant amount side-product sludge, which currently as CO₂ capture agent, binder, material, inorganic synthesis, <i>etc</i>. this review, potential other areas highlighted.<br> bibliography includes 310 references.

[¹³C+D] Double Labeling with Calcium Carbide: Incorporation of Two Labels in One Step

Chemistry - An Asian Journal, Год журнала: 2022, Номер 18(3)

Опубликована: Дек. 19, 2022

D-labeling is a valuable tool in advanced synthetic chemistry and pharmacy. However, D-incorporation significantly complicates the identification of products. In fact, D labels are invisible 1 H-NMR spectra cause undesirable splitting 13 C-NMR which decreases detectable limits. At same time, 2 not effective for precise due to low sensitivity absence correlations with H atoms. Here, C-label was considered as an accompanying label D-label [13 C+D] unit D-containing sites track D-labels. C+D]-doubly labeled vinyl derivatives triazoles were synthesized using C-labeled calcium carbide source deuterium oxide D-label. The reaction occurred one-step manner accompanied situ doubly acetylene formation. Non-labeled, mono-labeled substrates isolated 25-80% yields.

Renaissance in Alkyne Semihydrogenation: Mechanism, Selectivity, Functional Group Tolerance, and Applications in Organic Synthesis

Chemical Reviews, Год журнала: 2025, Номер unknown

Опубликована: Апрель 25, 2025

Alkenes constitute a significant class of chemical compounds with applications in the bulk, pharmaceutical, or perfume industry. Among known methods olefin production, semihydrogenation C-C triple bond seems to be most straightforward one. Nonetheless, success this reaction requires full control over diastereoselectivity, eradication parasitic process over-reduction migration double formed, and achieving satisfactory functional-group compatibility. The review demonstrates developments field alkyne period 2010-2022, selected papers published 2023 2024, emphasizing solutions above-mentioned limitations. We discuss mechanistic aspects transformation, including those related unconventional systems. includes examples organic synthesis, confirming considerable utility process. Finally, strategies enhance catalyst selectivity are summarized. For reader's convenience, we provided graphical guidebook catalytic systems, illustrating efficiency particular method.
