“…There is a method [12] for monoglycerides obtaining using amidation of linseed oil with diethylenetriamine at temperatures of (413-453) K and different molar ratios of components. The disadvantage of this method is many stages, the need and complexity of mono-and diglycerides separation, the use of diethylenetriamine.…”

Fatty acid monoglycerides are a valuable component of the products of various industries. The emulsifying ability of monoglycerides is used in cosmetic, pharmaceutical, and food production. The process of fatty acid monoglycerides obtaining by the reaction of vegetable hydrogenated fat (salomas) with glycerol (glycerolysis method) has been studied. Potassium glycerate is used as a catalyst, which is characterized by high efficiency and safety of production and use. A feature of the work is the study of the dependence of the yield and melting point of monoglycerides on the technological parameters of glycerolysis. As a raw material, hydrogenated refined fat according to DSTU 5040 (CAS Number 68334-28-1) was used: melting point – 48 °C, mass fraction of moisture and volatile substances – 0.08 %, acid value – 0.25 mg KOH/g, peroxide value – 2.8 ½ O mmol/kg. In all experiments, the glycerolysis temperature was 180 °C, the catalyst concentration – 0.5 % in terms of metal. Rational conditions for glycerolysis were determined: duration (90 min.) and glycerol concentration (50 %). Under these conditions, the monoglycerides yield was 32.9 %, melting point – 61.5 °C. The mass fraction of free glycerol in monoglycerides was 1.0 %, acid value – 2.2 mg KOH/g. The efficiency of monoglycerides obtaining using potassium hydroxide and glycerol mixture as a catalyst under certain rational conditions has been studied. The monoglycerides yield of 30.1 %, melting point of 59 °C were obtained. Therefore, the use of potassium glycerate catalyst is more efficient. The results of the study make it possible to improve the technology for the production of fatty acid monoglycerides using a new catalyst and use resources rationally

“…The Kc keys for each user are calculated by the AuC of the home network and transmitted to the VLR as part of a set of triplets, where each triplet and, accordingly, the key Kc, is assigned a key number -CKSN. In some implementations, algorithms A3 and A8 are combined into a single algorithm A38, which uses RAND and Ki to generate Kc and SRES [9]. Unlike A3 and A8, which may be different for each individual operator, A5 is selected from a list of 7 possible options.…”

“…If the network and the mobile station do not have common versions of A5, the connection must continue in open mode or the connection will be lost. Algorithm A5 uses a 64-bit key Kc and a 22-bit TDMA frame number to compute the two 114-bit encryption words BLOCK1 and BLOCK2, which are used in transmission and reception, respectively [8]. Encryption words -EXORed with 114 bits of data in each frame.…”

The analysis of mobile communication standards is carried out, the functional structure and interfaces of interaction between the structural elements of the cellular network are considered. To understand the principle of communication according to the GSM standard, a block diagram of a mobile switching center (MSC), base station equipment (BSS), control and service center (MCC), mobile stations (MS) is presented. The main algorithms for ensuring the confidentiality and security of mobile subscribers' data, in different types of standards, as well as the vulnerabilities of information flows are considered. In particular, the following dangerous types of attacks have been identified, to which mobile network subscribers are sensitive: sniffing; leakage of personal data; leakage of geolocation data; spoofing; remote capture of SIM-card, execution of arbitrary code (RCE); denial of service (DoS). It is established that the necessary function of the mobile network is the identification of subscribers, which is performed by IMSI, which is recorded in the SIM card of the subscriber and the HLR of the operator. To protect against spoofing, the network authenticates the subscriber before starting its service. In the case of subscriber identification, the subscriber and the network operator are protected from the effects of fraudulent access. In addition, the user must be protected from eavesdropping. This is achieved by encrypting the data transmitted over the radio interface. Thus, user authentication in UMTS, as well as in the GSM network, is carried out using encryption with a common key using the "hack-response" protocol (the authenticating party sends a random number to the authenticated party, which encrypts it according to a certain algorithm using a common key and returns the result back).
