The Construction On The Scenic And Interactive Virtual Organic Chemistry Laboratory

With the development of computer technology and network technology, as the platform of data sharing, equipment sharing, experimental teaching, distance education, technical exchanges, joint research and collaborative work, virtual laboratory has gradually become a hot topic in research and application at home and abroad in recent years. At present, the virtual laboratory is moving in the direction of professional development, virtual organic chemistry laboratory is causing the wide attention of people for its unique role, especially the diversity and complexity in organic chemistry experiment, also makes the development of virtual organic chemistry laboratory more challenging. The prior organic chemistry virtual laboratories were based on a specific experimental process simulation, so scene, simulation and interaction were seriously insufficient and they needed to be constructed again if experiment process was slightly altered. The lack of openness and extensibility can not meet the needs of development.First, based on the current research status of virtual laboratory and theoretical analysis of construction, the organic chemistry virtual laboratory was designed on the whole and then scenic and interactive virtual organic chemistry laboratory was constructed by Flash CS3and ActionScript3.0. The virtual laboratory is provided with a strong sense of the scene and immersion and breaks the virtual scene model with single point of previous organic chemistry virtual laboratories. The platform contains a total of seven complete organic chemistry experiments, through the real-time transmission of parameter, the operator ultimately will get flexible experimental yield under different experimental conditions in the whole experiment process of weighing, measuring, adding drugs, organic reaction, separating and distilling. The use of "contact" technique on the connection of virtual reaction device realizes the high interaction and fluency of the operation. The thought that animation is made by program codes is used on the accurate simulation of virtual experimental operating process, which achieves the organic combination between accuracy and interaction of experimental operation."Instant yield" monitors the reaction process, which can trigger operator to think the reaction process of thinking and improve the ability to explore experimental regularity.In this paper, take acetate preparation experiment for example, a new constructional pattern that is model and easy to expand is proposed based on the similar material, and independent simulation of four experiments and different results under the same universal frame is implemented so successfully that the function of virtual laboratory is significantly enhanced. The model mentioned opens up a new effective way on developing virtual other categories (such as esters, alcohols, halohyrocarbons, amines) of virtual laboratories.
