Usage

General Description

2-(t-butyl)-3-chloromethyl-4,6-dimethylphenol, also known as PCMX, is a chemical compound with antimicrobial properties. It is commonly used in a variety of personal care products, including soaps, lotions, and hand sanitizers, as well as in industrial and healthcare settings for disinfection and sanitization purposes. PCMX works by disrupting the cell membranes of microorganisms, leading to their destruction and preventing their growth. It is effective against a wide range of bacteria and fungi, making it a popular choice for use in products designed to kill or inhibit the growth of harmful microorganisms. However, it is important to use PCMX in accordance with safety guidelines and regulations, as overexposure to the compound can lead to irritation of the skin, eyes, and respiratory system.

Method for preparing antioxidant @datdatdatin intermediate without solvent method

The invention relates to a method for preparing an antioxygen 1790 intermediate through a solvent-free method. The intermediate is specifically 2,4-dimethy-6-tertiary butyl-3-chloromethyl phenol. Thepreparing method of the antioxygen 1790 intermediate comprises the steps of reacting 2-4-dimethyl-6-tertiary butyl phenol, paraformaldehyde and concentrated hydrochloric acid under the effect of a catalyst at the room temperature, and in the reaction process, continuously introducing gas HCL, wherein the catalyst is a mixture of an ionic surfactant and a nonionic surfactant. The conversion rate ofraw materials is high, and the conversion rate of 2,4-dimethy-6-tertiary butyl-3-chloromethyl phenol can reach 99% or above; a solvent-free technology is adopted, and compared with an existing technology of adopting haloalkane as a solvent, the method has obvious environmental protection performance and low toxicity; the ionic surfactant and the nonionic surfactant are compounded for a catalysisreaction, the dosage of the catalysts is sharply lowered, and the cost is saved; the reaction can be completed simply under the room temperature, and the condition is mild.

Synthesis method of antioxidant 1790

The invention discloses a synthesis method of an antioxidant 1790 and belongs to chemical field. By adoption of the synthesis method, the problems of serious pollution, low raw material utilization ratio and high cost in the existing method are solved. The synthesis method is implemented by three steps of: (1) preparation of 4-tert-butyl-3-hydroxyl-2,6-dimethyl benzyl alcohol, wherein 2,4-dimethyl-6-tert-butyl phenol, concentrated hydrochloric acid and paraformaldehyde are stirred at the temperature of 40 DEG C and return for 50 hours to obtain 4-tert-butyl-3-hydroxyl-2,6-dimethyl benzyl alcohol, and the product does not need to be purified; (2) preparation of 4-tert-butyl-3-hydroxyl-2,6-dimethyl benzyl chloride, wherein hydroxyl groups of the 4-tert-butyl-3-hydroxyl-2,6-dimethyl benzyl alcohol are chloro-substituted by thionyl chloride to obtain the 4-tert-butyl-3-hydroxyl-2,6-dimethyl benzyl chloride, the product can be obtained by crystallization of methyl benzene and methyl alcohol, and after removal of a solvent, the crystallized mother liquor can be continuously used as a raw material; and (3) preparation of a 1790 product. The synthesis method disclosed by the invention has the advantages that the production cost is effectively reduced, the steps are simple and easy to operate, and the generated waste water is less, so that the industrial production is easy.

Process for tris(aralkyl)phosphines

In a solution that is free of bases and free of oxygen and which contains at least four molar proportions of the reactant tris(hydroxymethyl)phosphine for every three molar proportions of an aralkyl halide reactant, the following reaction produces tris(aralkyl)phosphine product: after separation of the phosphine product, the phosphonium salt by-products can be converted to tris(hydroxymethyl)phosphine by the addition of a base.
