Abstract: The objective of the experiment was to prepare Benzilic acid by multistep synthesis starting with benzaldehyde. In this setup however‚ product of the first step‚ Benzoin‚ is provided thereby omitting the first step involving the conversion of benzaldehyde. For this experiment‚ the microscale techniques of reflux‚ crystallization‚ and melting-point determination were used. Utilizing these techniques a product yield of 93% for benzil and 57% for Benzilic acid was obtained‚ as well as

Wall and floor tile used for interior and exterior decoration belongs to a class of ceramics known as whitewares. The production of tile dates back to ancient times and peoples‚ including the Egyptians‚ the Babylonians‚ and the Assyrians. For instance‚ the Step Pyramid for the Pharoah Djoser‚ built in ancient Egypt around 2600 B.C. ‚ contained colorful glazed tile. Later‚ ceramic tile was manufactured in virtually every major European country and in the United States. By the beginning of the twentieth

Paper is a thin material produced by pressing together moist fibers‚ typically cellulose pulp derived from wood‚ rags or grasses‚ and drying them into flexible sheets. Paper is a versatile material with many uses. Whilst the most common is for writing and printing upon‚ it is also widely used as a packaging material‚ in many cleaning products‚ in a number of industrial and construction processes‚ and even as a food ingredient – particularly in Asian cultures. Paper‚ and the pulp papermaking

All surfaces should be kept clear of unnecessary equipment or clutter to ensure regular and thorough cleaning can occur. The most important component of an effective cleaning programme is the regular removal of dust from all horizontal surfaces. GPD and water should be used for all environmental cleaning

process of making paper involves two stages: the breaking up of raw material (which contains cellulose fibre) in water to form a pulp (a suspension of fibres)‚ and the formation of sheet paper by spreading this suspension on a porous surface‚ and drying‚ often under pressure. Hand papermaking has enjoyed a major revival over the past 30 years‚ using new and innovative approaches. Handmade paper has a unique texture and an individual quality that makes it not only a surface to write‚ paint‚ or print

To overcome this fabric is extended in widthwise to some extent in the stenter machine during the finishing process. Then it is subjected to the preshrink process. Various mechanical and chemical finishes have been adopted on cotton fabric to overcome shrinkage during subsequent washing. All the chemical and mechanical finishes have got some disadvantages like DMDHEU releasing formaldehyde which affects skin. Hence a chemical such as Resil CLS (modified glyoxal) can be given on 100 % cotton
