The synthesis of o-chloronitrobenzene and o-nitro aniline diphenylamine as a model to investigate the best conditions for coupling reaction of carbon and nitrogen. The reaction conditions are: at 190 \u2103, will excessive nitrochlorobenzene into aniline and alkali sodium bicarbonate solution, with the PEG-800 as the catalyst for 24 hours, and then re-crystallized products. In which the molar ratio of each substance nitrochlorobenzene: aniline: PEG-800: NaHCO3 = 1:2:0.12:0.55, the resulting yield was 80.3%. Determined by IR structure of the product, the product of the capillary melting point determination, using liquid chromatography analysis of product purity and content. By measuring, determine the best carbon and nitrogen coupling reaction conditions. The reaction is simple, raw materials, low cost, mild reaction conditions, can be applied to industrial production.

in April on 30, the Patric · wieden (Patrick Vuitton) with French President Sa Keqi the same place, attended the Shanghai World Expo France hall openning ceremony.
Even if stands nearby president, wears the refined eyeglasses, the full face beard Patric's elegant demeanor is not inferior.But several dozens years ago, he may not want to be able “the scenery”.His ideal only is works as a veterinarian.The grandfather attempts continuously with each method convinces him, said in his blood the flow family commercial soul.After the grandfather died, Patric's idea changed - - has taught other people as the LV family five dynasties, Patric was destined to be able to hold the post of the LV culture spokesman.
His family and the World Expo quite have the origin.143 years ago, Patric's ancestor Louis · wieden first time attends the Paris World Expo, but and obtains the award item the reputation to inspire greatly.But that was the too remote matter, the family members all were unable to confirm that time won a prize is any product, therefore the official view was “has the possibility is extremely a section pessimistic manta material quality flat topping suitcase”.
Is same with other apprentices, Patric has used the near 20 year time, how studies becomes a handicraftsman.He wants to go nearly every day to be located the Paris suburb a labor workshop, that is the labor workshop which the Louis · wieden myself establish.Patric becomes a carpenter apprentice first, then has become a furs artisan, how finally only then studies makes a suitcase.
This time, he brings LV to participate in all previous years World Expo exhibit article, comes Shanghai to conduct the display.The participation most ancient box, produced in 1887.When cuts the ribbon to the display, he is likely others such casual knife cuts, but is mentions a colored ribbon jiao to observe first, under the blank the knife, cuts the next section to have the integrity LV mark colored ribbon, folds carefully admits the pocket.It is said, he each time attends the ribbon cutting ceremony, all must leave behind section of colored ribbons to take the commemoration.
The Patric · wieden participates in the Louis wieden hundred year world abundant reviews.
The tradition and the innovation union, is the development idea which LV persisted throughout.As the ordering department's people in charge, Patric also persist this tradition.Several years ago, he the charitable auction which conducted for the Chinese some fashion magazine designs one section to have the LV mark Chinese mahjong, is patted by singing star that England by the high price.Perhaps looked like in him that, the mahjong specially has the Chinese color equally interesting apparatus.
Although often together attends each kind of activity with the star jorum, Patric persists the maintenance low key individual life.Trip of regarding the this Chinese, he has only accepted a television media interview request in a month, and stated did not reply concerns question which individual life and the company manage, only discusses LV the culture.However when newspaper reporter accidentally meets him in an activity, and asks him with China's young people to say when several speeches, he takes pen in hand joyfully writes down: Will express I most best wish to Chinese youth's future.
“Patric Mr. is a very amiable person.” The staff tells reporter, even if all can enjoy the distinguished guest treatment to where which the private car sends and picks up, Patric regarding the not too far traveling schedule, likes walking.
Patric already was LV has worked for 34 years.When was asked when he to the luxury goods the understanding is any, he said that, is travels in a person comes back, own pet dog by far runs welcome oneself; Or alone enjoys hoists the sails the marine pleasure.In brief, luxuriously regarding him, freely passed these short and the happy time.
Again some 12 days, Patric had to return to him to work 34 year Paris suburb labor workshop.In there, the people can call him likely the ancestor “Louis Mr.” such, calls him “Patric Mr.”.But Patric's Mr. work, is cultivates LV with the traditional means the apprentice, that needs several years at least, is “the careful work”.

April 30, Patrick Wei Teng (Patrick Vuitton) and with French President Nicolas Sarkozy, to attend the Shanghai World Expo opening ceremony of the French Pavilion.
Even standing next to the president, wearing glasses gentle, bearded face Patrick's style no less. May be several years ago, he thought to be so "beautiful." His ideal is only when a veterinarian. Grandfather has been trying various ways to convince him that his blood flow with the soul of the family business. Grandfather after the death of Patrick's idea of change - the fifth generation descendant of the family as LV, Patrick fate will serve as spokesperson LV culture.
His family and Expo roots. 143 years ago, the ancestors of Patrick Louis Vuitton for the first time the World Expo in Paris, and received awards and became famous. But that is too long to do, and so family members can not confirm that is what winning in the end product, so the official statement was "most likely is a gray waterproof canvas material with a flat roof luggage."
Like other apprentices, Patrick spent nearly 20 years to learn how to become an artisan. He almost every day and a workshop outside Paris, that is Louis Vuitton, I created the workshop. Patrick first become an apprentice carpenter, then became a leather goods maker, and finally learn how to make a suitcase.
This time, he took part in the previous LV Expo exhibits to the exhibition held in Shanghai. Exhibition of the oldest boxes, produced in 1887. When the ribbon-cutting ceremony for the exhibition, he was not as casual as people go for a scissors, but the first mention ribbon corner look, the space under the knife, cut a ribbon with a complete LV tag, carefully stacked in your pocket. It is said that every time he attended the ribbon-cutting ceremony, should leave a ribbon as a souvenir.
Patrick Tang Wei attend the Expo Review Louis Vuitton years.
Combination of tradition and innovation is the development of LV always adhere to the concept. As a custom department head, Patrick also maintains this tradition. A few years ago, he organized a Chinese fashion magazine designed a charity auction of Chinese mahjong with LV tag, singer Na Ying was photographed at high prices. Perhaps in his view, Mahjong is a Chinese style, like a particularly interesting appliances.
Although often present with the star to pop up with various activities, Patrick insists on keeping a low profile personal life. For this trip to China, he received only a month ago, a television media interview requests, and the statement did not answer questions about personal life and corporate business, but only the LV culture. However, when the reporter activity in a chance encounter him and ask him to young people in China and say a few words, he was pleased to pick up a pen to write: the future of the Chinese youth to express my best wishes.
"Mr. Patrick is a very amiable man." Staff told reporters, even where the guests can enjoy free shuttle service to be
