Preparation and Characterization of Polyallyl polyether of allyl sucrose Mukesh C Patel, Zalak J Patel Pramukh Swami Science and H D Patel Arts College, Kadi, HNG University Abstract: Allyl sucrose was prepared by using sucrose, allyl chloride, NaOH and DMSO. This novel method is less time consuming and required less solvent than other methods. The prepared product is characterized by Fourier Transform Infrared (FT – IR), 1H-NMR, MASS Spectroscopic techniques and Element analysis (C, H, N). Key words: allyl sucrose, allyl chloride, sucrose Introduction: Allyl sucrose is used for different applications like; coating material, medicines, cosmetics, epoxy resins, etc. [1]. These compounds can be used as film-forming materials/plastic compositions …show more content…
of sucrose, 88.5 lb. of allyl chloride, 46.2 lb. of sodium hydroxide and 23.1 lb. of water by Griffin, Willard, Sinnamon, Edwards and Redfield, Ind. Eng. Chem., 43, 2629 (1951) [5]. The process of allyl sucrose is described by Zief and Yanovsky, Industrial and Engineering Chemistry, vol. 41, pp. 1697-1700 (August 1949). In this sucrose is reacted with an allyl halide in the presence of excess of a strong alkali [7]. The conventional method is given by Tang Yanfeng, Zhang Shufen and Yang Jinzong, Chinese J.Chem.Eng.13(6) 835-836 (2005) [1]. Sucrose is treated with allyl chloride in the presence of caustic soda (NaOH). In this work DMSO is used for preparation of allyl sucrose. After the end of reaction there is no need of column chromatographic process for isolate allyl …show more content…

We are all aware of sugar, the sweet delicious substance commonly used in food and beverages, but table sugar is not the only sugar there is. There are many artificial sugars that many people now-a-days aren’t aware of. In this research paper I will be identifying four different types of synthetic sugars which are: Saccharin, Aspartame, Sucralose, and Sodium cyclamate. Synthetic sugars, or artificial sweeteners, have both positive and negative effects that can either make a big impact in our body or a small impact. Synthetic sugars can be used in many ways but are most commonly used in regular everyday foods and beverages or they can be mixed with other artificial sweeteners. Synthetic sugars tend to look very similar to real sugar so sometimes it may be hard to distinguish them with the naked eye.
Poly isobutylene, which makes the inner lining of a tire and also a basketball is one of the ingredients of gum base. Methyl Vinyl Ether-Maleic Anhydride Copolymer is very controversial over its safety
Aspartame has been known as one of the most famous sweeteners and additives to food. Since its discovery in 1965-1969, it has now been developed into a commercial product in which several products use it to enhance its sweetness and taste. Because of this, it has also been a very prosperous commercial product where its company developers get much profit on. Nonetheless, it has been the subject of issue and controversy. Several reports and studies rebuke the suitability of it being a food product stating that it is more known as a poison. Therefore, in this essay, the advantages and limitations of Aspartame as a chemical food additive will be analyzed and evaluated with regards to Economic and environmental factors. Also, the physiological effect of this chemical additive will be looked upon and discussed.
The mixture was poured through a weight filter paper and Sucrose washed with a 5ml of dichloromethane. The resulting solid was left in a breaker to dry for one week, to be measured. Left it in the drawer to dry out for a week and weighted it to find the sucrose amount recovered amount.
The synthesis of polymers starts with ethylene, (or ethene). Ethylene is obtained as a by-product of petrol refining from crude oil or by dehydration of ethanol. Ethylene molecules compose of two methylene units (CH2) linked together by a double carbon
A condenser and heat reflux was used to prevent reagents from escaping. Then the solid product was vacuum filtered. The product was recrystallized to purify it and the unknown
The worldwide demand for high potency sweeteners is expected to rise especially with the new practice of blending various sweeteners; the demand for alternatives is expected to increase. The sweet herb of Paraguay; Stevia rebaudiana Bertoni produces; in its leave;, such an alternative with the added advantage that stevia sweeteners are natural products. The sweet steviol glycosides have sensory & functional & properties superior to those of other high potency sweeteners. Stevia is to become a major source of high potency sweetener for the increasing natural food market in the coming future.
German Chemist Hans von Pechmann first synthesized Polyethylene by accident in 1898 by heating diazomethane. His colleagues characterized the waxy substance polyethylene due to the fact that they recognized that it consisted of long ethene chains. It was then first industrially synthesized by accident in 1933 by applying extremely high pressure to ethylene and benzaldehyde. Over the years, development of polyethylene has increased due to the additions of catalyst. This makes ethylene polymerization possible at lower temperatures and pressures.1
about, you’ll have to talk about what monomers and polymers are, what the entire process of
aspartame is used, small quantity is needed to produce the same amount of sweetness as sucrose. As a
By taking a Carbon Dioxide, rich substance and mixing it with a yeast, solution fermentation will occur, and then it could be determined if it is a good energy-producer. In this study glacatose, sucrose, glycine, glucose, and water were used to indicate how fast fermentation occurred. The overall result shows that monosaccharides in particular galactose and glucose were the best energy source for a cell.
