Sinochem International is to become a leading player in chemical trading, fine chemicals manufacturing and chemical logistics service. The board and staffs maintained "service with commitment" principal, united and forward looking, taking responsibility and hard working mentality. We achieved breakthrough in many areas. The total business size and value created is at historical high. The sales revenue was RMB10.981 billion, a growth of 37.21%. The net profit was RMB261.93 million, a growth of 0.64%. With the General Shareholders Meeting approval, the company paid RMB1.25 dividend for every 10 shares and provided additional bonus of 5 shares for every 10 shares. Other significant developments are our strategic change. The R & D initiative have achieved a number of inventions which are patented, the construction of new plants is going well, a number of fine chemicals plants is coming on-stream, significant investments in chemicals logistics were made with shore tanks and tankers fleet, the Taicang chemical park development project also gained substantial pre-development progress. All these development would provide us with a solid foundation for speedy progress in future.

Sinochem International cordially welcomes friendly cooperations with various circles both at home and aboard.

*We will try to satisfy your special need about its specification.

      For decades, a global chemistry research effort is under way to replace environmentally problematic liquid or halide-containing solid acids with environmentally friendly oxides as catalysts. The heteropoly acid, as an environmentally friendly acid, possesses the dual catalytic functions of strong acidity and oxidizing ability, and so its catalysis has attracted much interest since seventies. Our product, phosphotungstic acid, a classical heteropoly acid, is widely used to make catalysts due to their high acid strength, psuedoliquid behavior, and thermal stability. Mainly application study can be classified into the following several groups: hydration and dehydration, esterification and etherization, alkylation, acidylation, dealkylation and isomerization, polymerization, crack and dissolution, condensation and so on. The polymerization of tetrahydrofuran is a typical commercial process which uses phosphotungstic acid as catalyst in China and Japan.

      Our process for the manufacture of phosphotungstic acid is a novel non-solvent technique, with 200t/y capacity. our technique allows us to promise to offer you phosphotungstic acid with special specification which you need. Besides, we also have the process to manufacture other heteropoly acids, such as phosphomolybdic acid, and so on.

2. Styrene-ran-Maleic Anhydride Copolymers

Random copolymers of styrene and maleic anhydride (SMAH) are manufactured by processes similar to those used in polystyrene, i.e. polymerization in bulk, started by heat or peroxide. They have good chemical stability, good process formability, and high heat-distortion temperatures over 100 ºC. SMA218 can be used as compatilizers in polymer blends, alloys, composites such as PC/ABS, PA6/ABS, PA6/PPO, PC/PS, PA6/PS, AS/GF, ABS/GF etc. Now in China, SMA218 has been used to mobile phone shell, fan vane, instrument panel framework and so on in many plastic factory.

3. SPEO-1TM double metal cyanide catalyst

SPEO-1TM is the double metal cyanide (DMC) complex catalyst with high performance for preparation of polyether polyols. It has been commercialized for several years with a capacity of 1t/a. The catalyst can be employed in polymerization of propylene oxide and random copolymerization of propylene oxide and ethylene oxide. In addition, aliphatic alcohols such as n-butanol and n-octanol can be used as a starter together with this catalyst for preparation of high molecular weight polyether with mono hydroxyl end group.

As compared with KOH widely used in polyether production, the polyether polyols manufactured with SPEO-1TM exhibit very low unsaturation, narrow molecular weight distribution and high functionality. Meanwhile, the high molecular weight polyether polyols can be prepared with this catalyst.

SPEO-1TM can be used as a drop-in catalyst for revamping the existing plant to increase its capacity by >30% without any modification. Furthermore, the the production cycle, energy comsumption and raw materials cost can be reduced with this catalyst since no purification of polyether polyols is required.
