| Technique：Synthesis method for large grain size latex |
| Country：[CN] |
Application Domain：[chemical industry] |
| Brief： |
The synthesis method of large-grain acrylic latex includes the following steps: 1. adding emulsifier in 0.01-0.09 wt% of total amount of reaction monomers in polymerization still; 2. adding monomer in 30-60 wt% of total amount of reaction monomers in polymerization still; 3. adding initiator in 0.2-0.8 wt% of total amount of reaction monomers in polymerization still; and 4. adding water; then heating to make reaction for 15-20 min, and adding emulsifier in 0.2-0.8 wt5 of total amount of reaction monomers and residual 40-70 wt% monomer, said partial emulsifier and monomer can be added once or in several times, constant temp. reaction for 3-5 hr to obtain latex whose grain size is 200-600 nm. |

| Technique：ZHUHAI PURIFIED TEREPHTHALIC ACID PLANT |
| Country：[CN] |
Application Domain：[chemical industry] |
| Brief： |
It is intended that the production capacity of the PTA plant will be increased by 150,000t/yr. This will mean that the plant will have a total capacity of about 350,000t/yr when it goes into full production. The plant uses acetic acid as a feedstock, so it may decide to buy this from BP Amoco's new acetic acid plant in Chuanwei in Chongqing province. Alternatively, it may find another source.
The expansion to the existing plant was approved by the Chinese State Development Planning Commission in 1999, and completion of the facility is expected in early 2003. The project was delayed for a period because of its poor market prospects at that time. The decision to postpone came when Asian economy was in turmoil, as a result of the currency crisis that year. The estimated cost of the project is between $300 million and $400 million. |
