This paper presents a comparative experimental study on the frosting characteristics of an air source heat pump system that contains two operation modes, i.e., the vapor-bypassed evaporation (VB) mode and the conventional operation (CO) mode. For VB mode, a phase separator is installed inside the evaporator re-frigerant circuit to bypass vapor refrigerant, which can increase the average evaporation temperature for retarding frosting by reducing refrigerant pressure drop and decreasing the area of refrigerant inferior heat transfer coefficient region (mist flow region). According to the experimental results, under H2 con-dition (indoor: 20/15 degrees C; outdoor: 2/1 degrees C), as the initial refrigerant mass flow rate ranges 35-45 g / s , the VB mode yields 4.30-7.06% lower frost mass, 3.9-7.3% higher average heating capacity and 6.4-10.8% higher coefficient of performance (COP) over CO mode with the frosting duration of 60 min. Moreover, under H3 condition (indoor: 20/15 degrees C; outdoor:-7/-8 degrees C), the frosting duration is set as 100 min, and the VB mode obtains 9.67% lower frost mass, 7.0% higher average heating capacity and 13.3% higher COP over CO mode. Generally, the vapor-bypassed evaporation technique has a great application potential in retarding frosting and improving performance of an air source heat pump system especially under high heating capacity or low ambient temperature conditions.

The tumor suppressor transcription factor CCAAT enhancer-binding protein alpha (C/EBP alpha) expression is down-regulated in myeloid leukemias and enhancement of C/EBP alpha expression induces granulocytic differentiation in leukemic cells. Previously we reported that Styryl quinazolinones induce myeloid differentiation in HL-60 cells by upregulating C/EBP alpha expression. To identify more potent molecule that can induce leukemic cell differentiation we synthesized and evaluated new series of styryl quinazolinones, ethynyl styryl quinazolinones, styryl quinolinones and thienopyrimidinones. Thienopyrimidinones were found toxic and styryl quinolinones were found inactive. Ethynyl styryl quinazolinone 39 and styryl quinazolinone 5 were found active on par with the earlier reported analogues 1 and 2 suggesting that the 5-nitro furan-2-yl styryl quinazolinones find a real promise in leukemic cell differentiation. The improved potency of 5 suggested that further modifications in the 5-nitro furan-2-yl styryl quinazolinones can be at the phenyl substitution at the 3-position of the quinazolinone ring apart from the 5-position of the heteroaryl ring.

I found the field of Chemistry very interesting. Saw the article 2-Methyltetrahydrofuran as a Solvent of Choice for Spontaneous Metathesis/Isomerization Sequence published in 2019. Recommanded Product: Anthrone, Reprint Addresses Kajetanowicz, A; Grela, K (corresponding author), Univ Warsaw, Fac Chem, Biol & Chem Res Ctr, Zwirki & Wigury St 101, PL-02089 Warsaw, Poland..

A new protocol for ring-closing metathesis/isomerization sequence was developed. The reactions of selected dienes were performed in overheated 2-methyltetrahydrofuran at 120 degrees C and provided a wide range of cyclic vinyl ethers and amides with good yields and selectivities. Computational analysis suggests that the relative yield of products depends on a thermodynamically driven process on the basis of relative stabilities of isomers.

Recommanded Product: Anthrone. Bye, fridends, I hope you can learn more about C14H10O, If you have any questions, you can browse other blog as well. See you lster.

Hypothesis: It is expected that incorporation of 2, 2, 6, 6-tetra-methyl piperidine-N-oxyl radical (TEMPO) and an imidazolium bromide bearing hydrophilic triethylene glycol (TEG) groups on Fe3O4@SiO2 core-shell may not only result in a novel highly water-dispersible/magnetically separable multi-functional catalyst system for metal-free aerobic oxidation of alcohols, which operates through a synergistic relay pathway, but it could potentially provide a strong platform for simultaneous separation and recycling of all components. Experiments: The catalyst was prepared by anchoring TEMPO moieties onto a magnetic core-shell Fe3O4@SiO2 functionalized with an ionic liquid bearing TEG groups. The materials was characterized using transmission electron microscopy, Fourier transform infrared spectroscopy, nitrogen adsorption-desorption isotherms, thermal gravimetric analysis, and elemental analysis. The performance of the catalyst was evaluated and quantitatively measured in the aerobic oxidation of alcohols in water. Findings: The catalyst exhibited excellent and stable colloidal dispersion in water and high performance in the aerobic oxidation of various types of alcohols under metal- and halogen-free reaction conditions. As hypothesized, strong synergistic effect between functionalized components was seen in the described reaction. The catalyst displayed excellent dual-adjustable-selectivity in the oxidation of primary alcohols to either the corresponding aldehydes or carboxylic acids by tuning the reaction solvent and/or reaction time and excellent recycling behavior through a double-separation-strategy.

A novel helical poly(phenyl isocyanide) bearing Boc protectedl-proline pendants (poly-1(m)) was designed and synthesized. Removed the protecting Boc groups on thel-proline pendants led to the formation of helical polymer poly-2(m), which showed high optical activity owing to the preferred right-handed helix of polyisocyanide main chain. Optically active helical poly-2(m)showed excellent catalytic ability on asymmetric aldol reaction. Helical polymer catalysts exhibited enhanced stereoselectivity in aldol reaction compared to small moleculel-proline. Under the optimized aldol reaction condition, the enantiomeric excess (ee) and diastereomeric ratio (dr) values of the aldol reaction product were respectively up to 90% and > 20/1. Moreover, the helical polyisocyanide catalyst Poly-2(m)can be easily recovered and reused in the aldol reaction for at least five cycles with maintained its activity and stereoselectivity.

Herein, we disclose a unique directing effect of 9-substituted triptycenes in electrophilic substitution to achieve the regioselective functionalization of the triptycene core. The Hirshfeld population analysis was adopted to predict the selectivity in electrophilic substitution. TMS and t-Bu groups were found to considerably accelerate the reaction at C2 positions to produce C3symmetric isomers. Correlation between distortion and charge distribution within benzene rings was systematically examined.

Herein, we report a bioinspired catalytic system for the one-pot cascade oxidation of a native primary amine and an in situ generated non-native secondary amine. The catalyst consists of an o-quinone cofactor phd (1,10-phenanthroline-5,6-dione) and a copper ion and operates under ambient air conditions. Quinazolin-4(3H)-ones, which are common pharmacophores present in numerous pharmaceuticals and bioactive compounds, were synthesized in high yields. A detailed kinetic and mechanistic study elucidates the role of the catalyst in the multi-step oxidative cascade reaction.

A simple protocol to overcome the explosive pentafluoroethylation of carbonyl compounds by HFC-125 is described. The use of potassium (K) bases with triglyme or tetraglyme as a solvent safely yields the pentafluoroethylation products in good to high yields. The experimental results suggest that an encapsulation of the K cation by glymes as K(glyme)(2) inhibits the contact between the K cation and the reactive anionic pentafluoroethyl counterion, preventing their transformation into KF and explosive tetrafluoroethylene (TFE). The generation of sterically demanding [K(G3)(2)](+) and [K(G4)(2)](+) is an effective way as an unstable pentafluoroethyl anion reservoir.
