Indene, also known as benzocyclopropene, is a polycyclic aromatic hydrocarbon with low toxicity and irritation to human skin and mucous membranes. It exists naturally in coal tar and crude oil. In addition, indene is also released when mineral fuels are not completely burned. Molecular formula C9H8. Molecular weight 116.16. The benzene ring and cyclopentadiene in its molecule share two adjacent carbon atoms. It appears as a colorless liquid, does not volatilize in vapor, turns yellow when standing still, but loses color when exposed to sunlight. Melting point -1.8°C, boiling point 182.6°C, flash point 58°C, relative density 0.9960 (25/4°C); insoluble in water, miscible with ethanol or ether. Indene molecules contain highly chemically active olefin bonds, which are prone to polymerization or addition reactions. Indene can polymerize at room temperature, and heating or in the presence of an acidic catalyst can increase the polymerization rate sharply, and react with concentrated sulfuric acid to form secondary indene resin. Indene is catalytically hydrogenated (see catalytic hydrogenation reaction) to form dihydroindene. The methylene group in the indene molecule is similar to the methylene group in the cyclopentadiene molecule. It is easily oxidized and reacts with sulfur to produce a complex, which has a weak acid reaction and reducing properties. Indene reacts with metallic sodium to form sodium salt, and condenses with aldehydes and ketones (see condensation reaction) to form benzofulvene: Indene is separated from the light oil fraction obtained from the distillation of coal tar in industry.

Indene is mainly used to produce indene-coumarone resin. The raw material of indene-coumarone resin is the 160-215°C fraction distilled from heavy benzene and light oil fractions, which roughly contains 6% styrene, 4% coumarone, 40% indene, 5% 4-methylstyrene and a small amount of xylene, toluene and other compounds. The total amount of resin accounts for 60-70% of the Chemicalbook raw materials. Under the action of catalysts such as aluminum chloride, boron fluoride or concentrated sulfuric acid, indene and coumarone fractions are polymerized under pressure or without pressure to generate indene-coumarone resin. It can be mixed with other liquid hydrocarbons as a coating solvent. It can also be an intermediate of pesticides or mixed with other liquid hydrocarbons as a coating solvent.

A principal use of lithium hydroxide monohydrate is as a starting material for numerous other lithium chemicals such as lithium fluoride, lithium chloride, lithium bromide and lithium iodide. Since these materials are prepared in aqueous solutions, there is no particular advantage in using the anhydrous hydroxide for the preparation. Other salts of weak and strong acids may be prepared using lithium hydroxide as a starting material. The preparation of anhydrous lithium hydroxide has already been described.

Other Names:DL-Mandelic acid
Mandelic acid is a high molecular weight fruit acid with lipophilicity. Compared with the common fruit acid glycolic acid, mandelic acid has a certain antibacterial ability. At the same time, compared to common glycolic acids and lactic acids, its transdermal speed will be slower, which means that the irritation is less than that of glycolic acids. Its fat solubility increases, and the transdermal ability of the stratum corneum is improved. Like glycolic acid and lactic acid, mandelic acid also has a certain whitening effect.

Glyceryl monoLaurate (abbreviated as GML), corresponding to CAS 142-18-7, is a monoester compound formed by the esterification reaction of lauric acid (dodecanic acid) and glycerol (mainly composed of glyceryl monolaurate, often containing small amounts of diester and triester impurities). Glyceryl monoLaurate is a naturally occurring nonionic surfactant. Monolaurin is also a substance with multiple functions such as emulsification, antibacterial and nutritional, and is widely used in various fields.
Glycerol laurate is a white to pale yellow powder, thin sheet or waxy solid at room temperature, odorless or slightly oily. The melting point is approximately 63-66℃. Monolaurin is insoluble in water but readily soluble in organic solvents such as ethanol, glycerol, and vegetable oil. When heated (e.g., above 70℃), it can disperse in water to form an emulsion.
Monolaurin 142-18-7 possesses the typical characteristics of esters and can undergo hydrolysis reactions under acidic and alkaline conditions, generating lauric acid and glycerol. Glyceryl monoLaurate has good stability and is not prone to decomposition under conventional food and cosmetic processing conditions (such as heating and sterilization), and is highly compatible with most ingredients.

1. Food Industry (Core application field)
Natural food preservatives (antibacterial agents) : This is the prominent application of GML. Monolaurin has a significant inhibitory effect on various Gram-positive bacteria (such as Staphylococcus aureus, Listeria, Bacillus subtilis, etc.) and fungi (such as yeast, mold), especially showing excellent results against microorganisms that cause food spoilage. Monolaurin also has a certain inhibitory effect on Gram-negative bacteria (such as Escherichia coli and Salmonella) (and can be combined with other preservatives to enhance the effect). It is widely used in dairy products (yogurt, cheese, milk beverages), meat products (sausages, hams), pastries, beverages, condiments, etc., to extend the shelf life of food and without the potential risk of chemical preservatives.
Food emulsifier: Monolaurin, as a nonionic emulsifier, can improve the compatibility of oil and water systems in food, evenly disperse oils in the aqueous phase, prevent stratification and sedimentation, and enhance the texture and stability of food. For example, when used in baked goods such as cakes and bread, it can improve the extensibility of the dough and make the finished product soft in texture. Monolaurin can be used in ice cream and chocolate to enhance fineness and melting stability.
Nutritional fortifier: Lauric acid is an important source of medium-chain fatty acids in the human body, featuring rapid energy supply and low fat accumulation. GML can be used as a carrier of medium-chain fatty acids in infant formula foods, sports nutrition foods, etc., to supplement nutrition.

Spermidine is an endogenous polyamine. It is formed from putrescine by spermidine synthase. Spermidine (25 μM) inhibits the activity of the human inward-rectifying potassium channel Kir2.3 in a patch-clamp assay. It induces autophagy in HeLa cells when used at a concentration of 100 μM and increases the lifespan of D. melanogaster, yeast, and C. elegans. Spermidine (30 mM in the drinking water) reduces demyelination of the optic nerve and disease severity in a mouse model of experimental autoimmune encephalomyelitis (EAE). It reduces increases in blood pressure, left ventricular posterior wall thickness, and heart weight in salt-sensitive Dahl rats fed a high-salt diet, a model of hypertension-induced congestive heart failure. Formulations containing spermidine have been used as dietary supplements.

Picaridin is an insect repellent. It inhibits A. aegypti odorant receptor 2 (AaOR2) or AaOR8 in the presence of their odorant activators, indole and octenol, respectively, expressed in Xenopus oocytes (IC50s = 1,452 and 1,911 μM, respectively). Picaridin reduces the number of entries into a food chamber by female D. melanogaster in an olfactory-based choice assay. It acts synergistically with the non-pyrethroid insecticide pyrimiphos methyl to increase mortality of A. gambiae and reduce blood feeding when used at a concentration of 10 g/m2 on nets surrounding guinea pig cages. Formulations containing picaridin have been used as insect repellents against flies, mosquitoes, chiggers, ticks, and fleas.
