Ningbo Wanglong Technology Co., Ltd. is a national key high-tech enterprise established in 1992. Its industries span chemicals, food additives, vegetable farming, papermaking, packaging, real estate, wire and cable, and finance.

In 2009, the company was restructured into a joint-stock enterprise through investment and控股. It is located in the beautiful Yuyao Binhai New City by the Hangzhou Bay. The company has a registered capital of 101.8 million yuan and a total fixed asset investment of over 680 million yuan.

The company primarily produces downstream derivatives of acetic acid, which fall into four categories: food additives, pharmaceutical intermediates, pesticide intermediates, and intermediates for the printing and dyeing industry. Its production capacities include 50,000 tons of sorbic acid (potassium salt), 5,000 tons of vanillin, 70,000 tons of diketene, 160,000 tons of acetic anhydride, 50,000 tons of methyl acetoacetate, and 50,000 tons of ethyl acetoacetate—totaling seven products. The production capacity for sorbic acid will account for 50% of the global total, making it the world's largest sorbic acid production base. The diketene product will also become the world's largest production base. Additionally, it is the largest production base for acetic acid downstream derivatives in China.

The products are widely used in food, beverages, pharmaceuticals, pesticides, printing and dyeing, and other industries, meeting domestic and international market demands. This represents a key development direction in the fine chemical sector.
