Hudromentoxycarbonylation of isobutylene by means of carbon monoxide and spirits in the presence of palladium phosphine complexes
Annotation: The article is devoted to the study of the reaction of hydromentoxycarbonylation of isobutylene in the presence of palladium phosphine complexes in order to optimize the method of obtaining menthyl ether of isovaleric acid, which is the main component of the drug «Validol». The purpose of the article is to improve the methods of obtaining menthyl ether of isovaleric acid (the main active component of the drug "Validol") and to study the reaction of hudromentoxycarbonylation with l-menthol and carbon monoxide of isobutylene in the presence of homogeneous catalytic systems based on palladium phosphine complexes. The article presents studies on the content of validol from various types of raw materials by the method of GC analysis. In the commercial samples of validol obtained from natural l-menthol and industrial isovaleric acid (obtained as a result of the oxidation of "fermentation isoamyl alcohol"), there are 2 components (l-menthyl ether of l-menthol and isovaleric acid), additionally 2 % menthene hydrocarbon and 23 % L-menthyl ether of methyl ethylacetic acid. A probabilistic mechanism of the reaction of the hydromentoxycarbonylation of isobutylene with l-menthol and with carbon monoxide and in the presence of catalytic systems based on the studied palladium phosphine complexes is proposed.

On the application of CASE-methodologies at the stage of analysis and design of software tools
Annotation: Main problem: the globalization of the information sphere has led to a significant increase in the volume of stored and processed information. To increase the processing speed and provide information to the recipient, it is logical to increase the power of the equipment on which the information is processed. But such a path also leads to an increase in financial costs for continuous modernization or complete updating of computer equipment and application software. Purpose: an alternative solution to increasing the capacity of hardware and software may be to optimize the process of organizing data storage, and already at the stage of information analysis. At the initial stages of the task, a huge amount of information is collected and processed, which needs to be classified, to identify essential and non-essential information flows for the information system being developed, etc. The quality of functioning of the developed information system as a whole and its individual modules in particular will depend on how correctly and fully the structuring and systematization of data will be carried out. Methods: modern methodologies of conceptual design of information systems shift the emphasis from software implementation to analysis and modeling of the production environment. The tools used in the process of conceptual modeling allow you to automate the main part of the processes, including the development of program code in the format of templates (patterns), including the preparation of documentation for the software product being developed. Since modern methodologies and tools are based on the use of powerful graphical tools, this significantly increases the visibility and simplifies the process of making adjustments to the information system project, actually using the "Drag-and-Drop" technology. This allows you to redistribute the time spent on the implementation of the first stages of information system development, allocating more time to the analysis and design of the software environment at an abstract, conceptual level. Results and their significance: the stages of analysis and design do not require large financial costs and are more variable. Information at these stages is easier to adjust and change than, for example, at the stage of writing program code. In addition, it is at these stages that the most active interaction between the developer and the customer is carried out, where maximum visibility and variability of the project of the future information system is required. And the use of modern software design methodologies significantly increases the efficiency of the first stages of information system design.

Development of technological parameters for gluten-free pasta production
Annotation: The article is devoted to the development of technological parameters for the production of gluten-free pasta, as well as to the study of the influence of physico-chemical factors on the formation of the structure and organoleptic parameters of gluten-free pasta. The authors studied modern approaches to the production of gluten-free food in Kazakhstan. During the study, the main types of raw materials used in the production of gluten-free pasta of functional orientation were identified. For the production of a new product, a reasonable choice of raw materials and functional ingredients was carried out, the formulation and production technology were developed, all temperature and time modes were described, physico-chemical, organoleptic parameters of the new product were studied, a production flowchart was developed. The purpose of the article is to develop the technology of gluten-free pasta enriched on the basis of corn, rice flour and meeting the requirements for specialized food products, with the addition of functional and flavoring ingredients to expand the range of gluten-free products in the Republic of Kazakhstan. In experimental studies, the formula of a new gluten-free paste based on rice and corn flour with the addition of flaxseed flour, soy protein isolate «EdimCo», xanthan gum, dietary fiber (psyllium), Supermak booster was developed. The complex results of organoleptic and physico-chemical parameters of whole-grain flour for the production of new gluten-free pasta are presented. The results of organoleptic and physico-chemical indicators, as well as safety indicators of finished gluten-free pasta are presented. The article presents the technological parameters and time modes of the production process of fresh pasta, including the following basic operations: preparation of raw materials at t = 10 0C, kneading pasta dough at t = 40-45 0C, vacuuming at 40-10 kPa, pressing (extrusion) at 7 min, 10-12 MPa, drying and stabilization at 10-12 MPa, cooling of dried products t = 20-25 0C 4 hours, packaging of finished products at t = 35 0C and relative humidity 70 %.
