Soxhlet extraction
A Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the extraction of a lipid from a solid material. However, a Soxhlet extractor is not limited to the extraction of lipids. Typically, a Soxhlet extraction is only required where the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. If the desired compound has a high solubility in a solvent then a simple filtration can be used to separate the compound from the insoluble substance.

The document describes a Soxhlet apparatus, which is used to extract compounds from solids using solvents. It was invented in 1879 by Franz von Soxhlet to quantify fat in milk. It has a chamber that holds the solid sample and is filled with warm solvent from a distillation flask via a siphon. The solvent dissolves some of the desired compound and returns to the flask, repeating the process over hours or days to concentrate the compound. It is commonly used in pharmaceuticals, environmental analysis, and food testing to extract lipids, oils, and other compounds. While lengthy, it provides efficient, gentle extraction of compounds that are only slightly soluble in solvents.

It is useful for pharmaceutical, environmental, and foodstuff extractions, though it requires large volumes of solvent and time.
Soxhlet Extraction.pptx
The document describes the Soxhlet apparatus, which is used for extracting compounds from solids using a solvent. It discusses the key parts of the apparatus including the still pot, distillation path, thimble, siphon top, and condenser. The working principle involves heating the solvent to its boiling point, causing it to vaporize and condense on the thimble containing the solid sample. When the extractor fills, it siphons the now extract-containing solvent back to the still pot. This cycle repeats until the solid is fully extracted. The document notes advantages like high extraction efficiency but also disadvantages like long extraction times and large solvent usage. It also discusses automated Soxhlet methods that reduce extraction times and comparisons

Each method has advantages and suitabilities depending on the material and desired compound. Selecting the appropriate extraction technique is important to efficiently separate and obtain compounds of interest without degradation.
Soap manufacturing process
soap is a salt of a fatty acid,.
Consumers mainly use soaps as surfactants for washing, bathing, and cleaning, but they are also used in textile spinning and are important components of lubricants.
Soaps for cleansing are obtained by treating vegetable or animal oils and fats with a strongly alkaline solution

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

SOXHLET APPARATUS
- 1. SOXHLET APPARATUS Rashmi H.R M.Sc. pharmacology
- 3. SOXHLET APPARATUS • A Soxhlet extractor is lab equipment designed for processing certain kinds of solid. • These device allow for continuous treatment of a sample with a solvent over period of hours or days to extract compounds of interest. • Typically, a soxhlet extraction is only required where the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent.
- 4. INVENTION • It was invented in 1879 by a scientist named Franz von soxhlet • It was first invented for the quantification of fat in the milk. • Then it has been frequently used for the extraction of lipids in agricultural chemistry
- 5. COMPONENTS 1. Stirrer bar 2. Still pot ( the still pot should not be overfilled and the volume of solvent in the still pot should be 3 to 4 times the volume of the soxhlet chamber ) 3. Distillation path 4. Thimble 5. Solid 6. Siphon top 7. Siphon exit 8. Expansion adapter 9. Condenser 10. Cooling water in 11. Cooling water out
- 6. PROCEDURE • Normally a solid material containing some of the desired compound is placed inside a thimble made from thick filterpaper, which is loaded into the main chamber of the soxhlet extractor, the soxhlet extractor is placed onto a flask containing the extraction solvent. The soxhlet then equipped with a condenser. • The solvent is heated to reflux. The solvent vapour travel up a distilantion arm, and floods into the chamber housing the thimble of solid. The condenser ensures that any solvent vapour cools, and drips back down into the chamber housing the solid material. • The chamber containing the solid material slowly fills with warm solvent. Some of the desired compound will then dissolove in the warm solvent. When the soxhlet chamber is almost full, the chamber is automatically emptied by a siphon side arm, with the solvent running back to down the distillation flask. This cycle may be allowed to repeat many times, over hours or day.
- 7. • During each cycle, a portion of the non-volatile compound dissoloves in the solvent. After many cycles the desired compound is a concentrated in the distillation flask. The advantage of this system is that instead of many portions of a warm solvent being passed through the sample, just and batch of solvent is recycled. • After extraction the solvent is removed, typically by means of a rotary evaporator, yielding the extracted compound. The non-soluble portion on the extracted solid remains in the thimble, and is usually discarded.
- 8. APPLICATIONS It is the most useful apparatus for solid-liquid extraction in various fields such as • pharmacecutics • Environment and also • foodstuffs nowadays , soxhlet apparatus is still common and widely used as a reference and standard method in many laboratories for the extraction of oil from various materials.
- 9. Microwave assisted soxhlet extraction (MASE ) • Fat extraction from 1. Prefried and fried meat. 2. Fish and. 3. Bakery products. Microwave - integrated soxhlet extraction (MISE ) • Extract oil from 1. Olive seeds. 2. Oleaginous seeds, and 3. Bakery products.
- 10. ADVANTAGE & DISADVANTAGES advantages 1. Mechanically gentle process yet quite efficient extraction 2. Can perform elemental sulfur removal simultaneously (activated Cu ) disadvantages 1. Lengthly process ( more than 24 hrs ) 2. Reqire azeotropic mixture to ensure efficient extraction
