The invention discloses a preparation method of new crystal form tapentadol hydrochloride, which comprises the following steps of (1) converting (2R, 3R)-3-(3-methoxyphenyl)-N,N,2-trimethyl-amylamine hydrochloride by use of a demethylation reagent into the formula (III): (-)-(1R, 2R)-3-(3-dimethylamino-1-ethyl-2-methylphenyl)phenol; (2) salifying the compound of formula (III) with hydrochloric acid in a mixed solvent of acetonitrile and isopropyl alcohol to obtain a compound of formula (I): (-)-(1R, 2R)-3-(3-dimethylamino-1-ethyl-2-methylphenyl)phenol hydrochloride. By adopting the method disclosed by the invention, stable new crystal form tapentadol hydrochloride can be obtained; moreover, the process conditions are mild, the after-treatment is simple, the purity is high, the reaction cost is low, and industrial production is easy to realize.

The invention provides a structure of an anti-electric carbon mark pipe internally coated with stress evacuating glue, which comprises an inner layer body and an outer layer body, wherein the inner layer body is provided with a stress control material, and the outer layer body is an anti-electric carbon mark thermo-shrinking insulating material. As the inner layer of the anti-electric carbon mark pipe internally coated with the stress evacuating glue is provided with a continues stress control material, and the stress control material can be formed into effective bonding with the thermo-shrinking insulating material of the outer layer, so that the structure can effectively prevent a gap from generating, thereby effectively avoiding the hidden trouble that a power cable is broken down. Furthermore, the structural pipe of the anti-electric carbon mark pipe internally coated with the stress evacuating glue can perform radiation crosslinking with the high-energy electron beam or the high-energy ...

The invention provides a self-lubricating heat-shrinkable sleeve. The self-lubricating heat-shrinkable sleeve is characterized by comprising an inner layer body and an outer layer body, wherein the outer layer body is made of a heat-shrinkable material; and the inner layer of the heat-shrinkable sleeve is provided with a continuous lubricating material layer. Because the inner layer of the self-lubricating heat-shrinkable sleeve is provided with the continuous lubricating material and the lubricating material can form a continuous lubricating layer between the heat-shrinkable material and a protected object, the aim of a convenient sleeve is fulfilled effectively. In addition, the outer layer material of the self-lubricating heat-shrinkable sleeve can be subjected to radiation cross linking by utilizing high-energy electron beams or high-energy gamma rays and then expanded to form the heat-shrinkable sleeve by heating, so that an effect of heat shrinkage is achieved.
