Anhydrous An anhydrous material does not contain any water molecules. Many substances occur naturally as hydrates, compounds that have a specific number of water molecules attached to them. This water can often be removed by heating and/or vacuum to give the anhydrous material. Anhydrous materials can absorb water from their surroundings and find use as dessicants. Examples include those packets of silica gel you find in some consumer goods, as well as dehumidifying sachets used in clothes closets. When an anhydrous material reacts with water, this could release a large amount of heat, possibly leading to a heat or pressure buildup that could result in an explosion. 

The principal thing in connection with the employment of ionone is to discover its proper degree of dilution. In its natural state the body is so highly concentrated as scarcely to remind one of violets. This is the reason why it was placed in trade in the form of a 10 per cent, solution, and not in its pure state. This form has proved an exceedingly useful one. In using it for extracts, powders, sachets, etc., the solution must be further diluted and fixed with some orris oil, civet, and musk. ... 

This acid, CgH. CH. CH COOH, has a sweet and powerful odour, and can be used to advantage in many rose odours. It is recommended especially for perfuming powders and sachets. It is a crystalline compound, melting at 47° and boiling at 280°. It can be obtained by the reduction of cinnamic acid by means of sodium. 

Vapor phase inhibitors These are used for the temporary protection of new plant in transit or prior to commissioning. Volatile corrosion inhibitors such as cyclohexylamine derivatives are used. The plant must be sealed or contained to prevent rapid loss of the inhibitor. Sachets of these materials are placed in packing cases. Papers impregnated with them are available for wrapping steel items. These inhibitors are used primarily to protect steel.

Initially, the tank is charged with 25% of its volume with water and the appropriate amount of sanitiser. Products are introduced by adding a water-soluble sachet containing liquid or powder sanitisers or by adding a liquid product directly from a plastic bottle prefilled with the correct amount. This procedure accurately controls dosage rates and limits worker exposure. Products are diluted more than 400 times and are required to kill all pathogens within 15 minutes. 

Dimethyl fumarate (DMF) is used by producers as a biocide to kill moulds that may cause furniture or shoe leather to deteriorate during storage and transportation in a humid climate. Placed in sachets, which are fixed inside the furniture or added to the footwear boxes, DMF evaporates and impregnates the leather, protecting it from moulds. However, it has been found to seriously affect consumers who were in contact with the products. DMF penetrated through the clothes onto the skin of many consumers. Cases of severe health problems have been reported in UK, Finland, France and Poland. Although it is normally not used by tanneries, there are examples where tanneries have used DMF. 

Have you ever wondered about the content of the small packets of granules included in boxes of new electronic devices, leather products, or medications Or have you simply heeded the warning label to dispose of the sachet immediately The granular desiccants in these packets have particular physical properties that enhance their function as drying agents. A look at the chemical structure or chemical properties of these materials provides a better understanding of their capacity to control moisture. 

One litre of unfiltered water was rolled with a carbon sachet and 10g NaCI for 7 days. The carbon was then dried, ashed, digested in aqua regia and analysed by ICP-MS, for Ag, Au, Pd, and Pt. Field and analytical blanks, as well as duplicates were used in all analyses to ensure accuracy (Gray etal. 2001). 

A complex mixture of 10-methoxy-3,4,5,6-tetradehydro-18,19-dihydrocory-nantheol (17), 3,4,5,6-tetradehydroochropposinine (18), 10-methoxy-3,4,5,6-tetradehydrocorynantheol (19), and 3,4,5,6,18,19-hexadehydroochropposinine (20) has been isolated from the root bark of Neisosperma glomerata (Blume) Fosberg and Sachet (25). The approximative structure elucidation of alkaloids 17-20 was performed by H-NMR and mass spectral analysis of the unseparated mixture.

Silica gel is probably the adsorbent which is best known. Small sachets of gel are often included in packages of material that might deteriorate in a damp atmosphere. Sometimes a dye is added in the manufacturing process so that the gel changes colour as it becomes saturated. 

Q7 Each sachet of Dioralyte contains 0.47 g sodium chloride and 0.30 g potassium chloride. The amount in millimoles of chloride in one sachet is (relative atomic mass of sodium = 23 chlorine = 35 potassium = 39) ... 

Strontium ranelate is administered as 2 g once daily. In 24 weeks, the patient would require 6 packs of 28 sachets. If one pack of 28 sachets costs 47.12, 6 packs cost 282.72 (47.12 x 6).
