DODECYL PHENOL DDP - Study on lyotropic liquid crystal system containing polyoxyethylene (10) ether of dodecylphenol
from VIP
Author:
Abstract:
In this paper, the ternary system of nonionic surfactant dodecylphenol polyoxyethylene (10) ether (TX-10)/styrene/water is studied, and the ternary phase diagram is drawn, select the liquid crystal region as the research object, prepare a series of samples, take the texture photos, use the small angle X-ray diffraction method to determine the layer spacing when the various components in the liquid crystal change, combined with the comparison of ~ 2H NMR spectra and texture photographs and complementary analysis, it provides a new way to accurately distinguish the structures of liquid crystals. This is not only for the basic theory research, but also for the daily chemical industry and tertiary oil recovery has certain guiding significance.

DODECYL PHENOL DDP - Study on synthesis of dodecylphenol
Author:
Abstract:
The synthesis of dodecylphenol from Tetra-polypropylene and phenol is introduced in this paper. The reaction was determined to be a parallel-β-reversible reaction network by sampling and analyzing the materials in the process. From the experimental results, it is recognized that the ratio of phenol to olefin is the basic means to adjust the content of dialkylphenol in the product, and the activity of the catalyst is the key factor affecting the reaction depth, although time can make up for the low conversion rate due to the low activity of the catalyst to a certain extent, it is limited by the quality and cost of the product. Based on the experimental results, the empirical models of the reaction yield and the content of dialkylphenol were established, and the main results were expressed in the form of equal yield diagram.Key words:

from Palm Bridge research
Application (patent) number:
CN 200810222751
Public/Announcement Number:
CN101684066 A
applicant (patent):
Beijing Institute of Petrochemical Technology
inventor:
Shang Yuwei , Li Shuxin , Wenli Guo , a wave of , Li shaoran
Abstract:
The present invention relates to a process for the preparation of dodecylphenol, which is catalyzed by a catalyst in a petroleum ether solvent (when a Lewis acid catalyst is used), and the starting materials are phenol and triisobutylene, and the alkylation reaction is carried out. The reaction temperature is 20~90 ℃, the reaction time is 2~10 hours, and the ratio of phenol to trimeric isobutylene is 2.0~10.0:1 (molar ratio), the invention has the advantages of high product purity, good quality, high reaction yield, long service life of the catalyst and the like, and the preparation method of the invention can be applied to the current production process of dodecylphenol.
