The surfaces of P(AN-co-St), SP(AN-co-St), and MWCNTs were observed using scanning electron microscopy (JSM 6360 LA, JEOL, Tokyo, Japan) to examine their morphological structures. The composites were investigated at an angle of 11.1° with a particle size analyzer (Beckman Coulter, Miami, FL, USA) to study the distribution of particle sizes by dissolving the composites samples in water solution. Data were examined for 5 min at 20 °C with a refractive index 1.33 and viscosity 0.01 poise [3 (link),14 ]. FTIR and Raman spectroscopy were used to measure the influence of the prepared polymeric materials via a Shimadzu FTIR-8400 S (Kyoto, Japan) and Senterra Raman spectrometer (Bruker, Billerica, MA, USA), respectively.

All chemicals were purchased
from Merck or Aldrich with the highest purity available, and benzaldehyde
was used as a freshly distilled sample. The morphological, structural,
and compositional characterizations of the nanocatalyst1 were properly carried out using FESEM TESCAN-MIRA3, EDX Numerix
DXP-X10P, Philips CM30, Shimadzu FTIR-8400S, TGA Bahr company STA
504, and CHN Elemental instruments. Characterization of introduced
nanocatalyst1 was performed by transmission electron
microscopy (TEM, Philips CM30). A Shimadzu FTIR-8400S spectrometer
and a Bruker DRX-500 Avance spectrometer (ambient temperature in DMSO-d6) were used for recording FTIR, 1H NMR (500 MHz), and 13C NMR (125 MHz) spectra of products.
The analytical thin-layer chromatography (TLC) experiments were performed
using Merck 0.2 mm silica gel 60 F-254 Al-plates for observation progress
of reactions. All melting points were determined using a digital Electrothermal
9100 capillary melting point apparatus. The isolated yields of products
have been reported. All of the products, except6J , are
known compounds, and their physical, analytical, and spectroscopic
data were in agreement with the authentic samples.

UA (purity > 90%; Fig. 1 ) was purchased from Xi'an Ocean Biological Engineering Co., China. Silica gel (200–300 mesh) used in column chromatography was provided by Tsingtao Marine Chemistry Co., China. 3-O-acetyl-ursolic acid was prepared following the procedures described previously in detail26 (link). Other reagents at either analytical or chemical purity standards were obtained from commercial suppliers. Melting points were determined by using an electrically heated X-4 digital visual melting point apparatus. IR spectra and 1H-NMR spectra of synthesized compounds were recorded by using a Shimadzu FTIR-8400S and a BRUKER AV-400 or AVANCE III 500 spectrometer (using TMS as the internal standard in CDCl3 or DMSO-d6), respectively. Electrospray ionization (ESI) mass spectra of synthesized compounds were measured by using an Agilent 1100 IC/MSD Trap XCT.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
