Enthalpies of Dilution of Aqueous Tetradecyltrimethylammonium Bromide from 50 to 175 deg C

Enthalpies of dilution of aqueous tetradecyltrimethylammonium bromide have been measured from 0.3 to about 0.002 mol-kg-1 and from 323 to 448 K at 1.03 MPa.Different methods of obtaining the enthalpy of micellization from experimental data are examined.Enthalpies of micellization calculated from these methods disagree by large amounts.From consideration of the temperature dependence of the average aggregation number and multiple equilibria equations for micellization, it is shown that there is an enormous dependence of micellization enthalpy on aggregation number of a micelle.

Dynamical transition in a jammed state of a quasi-two-dimensional foam

The states of foam are empirically classified into dry foam and wet foam by the volume fraction of the liquid. Recently, a transition between the dry foam state and the wet foam state has been found by characterizing the bubble shapes [Furuta, Sci. Rep. 6, 37506 (2016)2045-232210.1038/srep37506]. In the literature, it is indirectly ascertained that the transition from the dry to the wet form is related to the onset of the rearrangement of the bubbles, namely, the liquid fraction at which the bubbles become able to move to replace their positions. The bubble shape is a static property, and the rearrangement of the bubbles is a dynamic property. Thus, we investigate the relation between the bubble shape transition and the rearrangement event occurring in a collapsing process of the bubbles in a quasi-two-dimensional foam system. The current setup brings a good advantage to observe the above transitions, since the liquid fraction of the foam continuously changes in the system. It is revealed that the rearrangement of the bubbles takes place at the dry-wet transition point where the characteristics of the bubble shape change.

Turpentine valorization by its oxyfunctionalization to nopol through heterogeneous catalysis

Turpentine is a mixture of monoterpene hydrocarbons obtained as a by-product in the paper industry. In this contribution we present its transformation process towards an alcohol named nopol, that is an important household product and fragrance raw material. Reaction conditions were established for the oxyfuntionalization of crude turpentine oil over Sn-MCM-41 catalyst for the selective conversion of beta-pinene to nopol. Synthesized materials were characterized by XRD, N2 adsorption, FT-IR, TEM and chemical absorption. The reaction was tested in 2 mL glass reactor with a sample of commercial turpentine with alpha-pinene (55.5% w/w) and beta-pinene (39.5% w/w) as main components and scaled up into a 100 mL Parr reactor, getting 92% conversion of beta-pinene and a nopol selectivity of 93%. The reusability tests showed that the catalyst can be reused 4 times without loss of activity. The results showed that 86% less solvent and 37.5% less paraformaldehyde can be used with turpentine, compared to the conditions used with beta-pinene for getting similar catalysts activity.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1119-97-7,MitMAB,as a common compound, the synthetic route is as follows.

General procedure: A 100mL round-bottom flask was equipped with a magnetic stir bar and a reflux condenser. To xylene (10.0mL), tetradecyltrimethylammonium bromide (1.1mmol) and a heterocyclic compound (1.0mmol) were added, followed bya solution of NaOH 50% (5.0 mL). The mixture was stirred at reflux temperature for 2-18 h. After completion of thereaction, the mixture was air-jet cooled to 25 C and TLC indicated the disappearance of the starting material. The reaction mix was treated with AcOEt (4 ¡Á 20 mL), and the organic phase separated and removed under reduced pressure. The residue was purified to analytical purity by column chromatography., 1119-97-7

NaOH (9mg, 0.225mmol) is added to the aqueous solution. After sealing, the sample is stirred at 60C for 8h to ensure completely soluble. The concentration of NBTA3- solution is calculated as 5¡Á10-5M. Then, dissolving different quaternary ammonium salts into NBTA3- solution. After stirring for 30minat room temperature (25C), NBTA3-/ammonium salts solution become transparent, which then is subjected to further instruments analysis.

General procedure: In a typical synthesis of DA-La(PW11)2, an aqueous solution of (2.0 g, 0.31 mmol) K-La(PW11)2 was dropped into a chloroform solution of (1.1 g, 3.75 mmol) DA-Br. A white precipitate formed after the addition of the whole K-La(PW11)2 aqueous solution and then the product was separated after a further 1 h of stirring. The product was washed twice with H2O and dried in air [9]. DDA-La(PW11)2, TDA-La(PW11)2, HDA-La(PW11)2 and ODA-La(PW11)2 were prepared with a similar procedure.
