China's production and application of PVP started late, since 1987 Henan Boai Open Source Fine Chemical Factory (now renamed Boai New Open Source Pharmaceutical Co., Ltd.) first realized the industrial production of PVP, the production and development of the product and the application of the research is more active, the development of a faster rate. In recent years, the gradual increase in the number of domestic manufacturers, so that China has become one of the few PVP producers in the world. Especially with the domestic maleic anhydride atmospheric decompression gas-phase hydrogenation and 1,4-butanediol dehydrocyclization production of r-butyrolactone development success and popularization and application, so that the production of GBL increased year by year, but also for the production of PVP provides the raw material base.
Domestic existing major PVP manufacturers and the main products: 1) Bo Bo New Open Source Pharmaceutical Company Limited: the leading products are PVP K series products (K12, K15, K17, K25, K30, K60, K90 and K120 powder, is the most complete domestic K series products manufacturers), PVP **** polymer (PVP/VA) series of products, povidone iodine (PVP-I) series of products, PVP/PA series of products, and PVP-IV. PVP/VA), PVP-I series products, crosslinking polymers, NVP monomer, 2-pyrrolidone, etc. (2) Hangzhou Nanhang Industry and Trade Co., Ltd: the leading products are 2-pyrrolidone, PVP K series products (mainly K30), PVP*** polymer (PVP/VA) series products, PVP I, cross-linked polymers such as PVPP. (3) Hangzhou Shenhua Science and Technology Co., Ltd: the leading products are PVP K series products, PVP/VA*** polymer, PVP-I. (4) Other domestic manufacturers: Anhui Hai Feng, Jiaozuo Yuanhai, Jiaozuo Meida, etc., the product is relatively single, mainly for PVP K30 and PVP-I two varieties. Domestic manufacturers of PVP production from 2006 to 2008 is shown in Table II below
Table II 2006-2008 PVP actual production within the country summary Quantity: tons Domestic manufacturers 2006 2007 2008 Bo Bo new open source 1000 1500 2000 Hangzhou Nanhang 1200 1400 1700 Hangzhou Shenhua 400 400 500 Other manufacturers 600 700 800 Total 3300 4000 5000 From the statistics in Table 1 and Table 2, it can be seen that, in recent years, the world's total production of PVP, Chinese products accounted for the world's total volume is still low, less than 10%, but with the gradual expansion of the production of domestic PVP production enterprises (domestic production in 2006-08 from 3200 tons to 5000 tons), product quality is improving, market share is increasing year by year, and the market share of PVP is growing. However, with the gradual expansion of domestic PVP production (domestic production increased from 3200 tons to 5000 tons from 2006 to 2008), the continuous improvement of product quality, and the increase of market share year by year (the global market share increased from 7.27% to 9.8% from 2006 to 2008), China's PVP industry should still have a great deal of room for development and prospects. With the domestic 1,4-butanediol and r-butyrolactone production capacity expanding in recent years, it provides abundant raw materials for the production and development of PVP, which makes it possible to further develop PVP series products.
